NMX-FCP-10 · ENGINEERED TO ORDER — FUEL-CELL HYBRID / SILENT FIELD POWER

Power the post. Silently.

Name: Fuel-Cell Hybrid Power System
Brand: Neometrix

Silent, low-signature power for a forward post. A fuel-cell + battery hybrid that runs on supplied hydrogen and delivers clean 230 VAC — near-silent, with a low thermal signature and no exhaust, where a diesel generator’s noise, heat and fuel runs are a liability. The fuel cell carries the base load, the battery covers peaks and a silent overnight watch, and an energy manager runs both. We integrate the system — storage, battery, power electronics, controls and the rugged enclosure; the stack and cells are bought in. Engineered to order — no specific delivered system is claimed.

Overview

The generator is the problem. Not the power.

A forward or high-altitude post needs electricity — for comms, sensors, lighting, a command post. The usual answer, a diesel generator, brings its own problems to exactly the places that can least afford them: it is loud, it runs hot, it smokes, and it has to be fed fuel constantly. A fuel-cell + battery hybrid delivers the same power with almost none of that signature or logistics — which is why it is being asked for.

Fig · 02 A fuel-cell stack — hydrogen and air in, DC power and water out, near-silently — illustrative, not a delivered installation

Why fuel cells, forward. A fuel cell makes electricity by combining hydrogen and air — the only outputs are power, water and a little heat. So it is near-silent (no engine), has a low thermal signature and no exhaust plume, and — unlike a diesel engine — it doesn’t lose power at altitude. For a post where noise, heat and a smoke trail are tactical liabilities, that is the whole point.

Hybrid, not just a stack. The fuel cell carries the steady base load efficiently; a battery absorbs peaks and transients and lets the fuel cell shut down for a genuinely silent overnight watch; and an energy manager orchestrates the fuel cell, the battery and any solar or DG input for runtime and efficiency.

Built on our hydrogen franchise. We have already built a power-to-power system around a fuel cell, storage and controls, and the whole hydrogen line behind it. This is that competence ruggedised and deployed — with the hydrogen supplied rather than made on site.

At a quiet observation post, a diesel generator can be heard and seen for kilometres. A fuel cell just makes power — no noise, no plume, no heat bloom. That difference is the product.

Why Fuel Cells Forward

Silent, cool, and no smoke trail

Fuel cells produce power, water and a little heat — near-silent, low thermal signature, no exhaust, and no altitude derate. Exactly the diesel generator’s liabilities, inverted — which is why forward and high-altitude posts want them.

Hybrid by Design

Fuel cell for base load, battery for the rest

The fuel cell runs the steady load efficiently, the battery covers peaks and a silent overnight watch, and the energy manager orchestrates both (plus optional solar/DG) — more runtime and efficiency than either alone.

Our Hydrogen Franchise, Ruggedised

We’ve built the fuel-cell system; this deploys it

Neometrix built a power-to-power system with a fuel cell + storage + 230 VAC + controls, and the whole hydrogen line. This is that, ruggedised for the field; the stack and battery cells are bought-in specialist.

Architecture

Hydrogen in, silent watts out.

The schematic shows the power chain — supplied hydrogen, the fuel-cell stack, the DC bus and battery, the inverter — and the hybrid that makes it silent and load-following. The detail panel sets out why a fuel-cell hybrid beats a diesel generator forward, and how this differs from our stationary P2P.

Arc · 01

Hydrogen Supply & Storage

Hydrogen supplied to the post as compressed cylinders or metal-hydride, stored and regulated to the stack. Supplied, not made on site — which is what makes it a deployable power source rather than a plant.

Arc · 02

Fuel Cell Stack

Combines hydrogen and air to produce DC power, water and a little heat, near-silently — the bought-in specialist heart, integrated with its balance-of-plant (air, cooling, humidification) by us.

Arc · 03

Battery Hybrid & DC Bus

A battery on the DC bus buffers peaks and transients, follows the load, and enables a silent watch with the fuel cell idle; the fuel cell recharges it. The hybrid is what right-sizes the stack.

Arc · 04

Power Electronics & Energy Management

DC-DC and inverter deliver clean 230 VAC / DC; the energy-management controller orchestrates fuel cell, battery and any solar / DG for runtime, efficiency and load-following.

Specifications

Reference system, sized to the load.

The parameters below describe a reference fuel-cell hybrid power system. The stack rating, the battery, the hydrogen stored and the runtime all follow from the load profile, the silent-watch requirement and the platform — a portable module, a field set, or an augmentation of an existing post.

Where field fuel-cell power goes wrong

In the hybrid and the hydrogen, not the stack. A fuel cell sized to the peak load instead of the base load is big, costly and inefficient — the battery is what should take the peaks; a system with too little stored hydrogen for the runtime silently runs out; and an enclosure not built for dust, cold and altitude fails where it is needed most.

That is why the fuel cell is sized to the base load and the battery to the peaks, the hydrogen is sized to the runtime and resupply interval, and the enclosure is built for the environment. Silent power is only useful if it lasts the watch.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 Why a fuel cell for a forward post instead of a diesel generator?

Because at a forward or observation post the generator’s by-products are tactical liabilities, and a fuel cell doesn’t produce them. A diesel generator is loud (it can be heard for a long way on a quiet night), runs hot (a clear thermal / infra-red signature), emits a visible exhaust plume and fumes, and needs a steady fuel resupply that is itself dangerous and revealing to run. A fuel cell makes power by an electrochemical reaction of hydrogen and air — no combustion, no moving engine — so its only outputs are electricity, water and a little low-grade heat. That makes it near-silent, gives it a low thermal signature and no exhaust, and — a real bonus in the mountains — it does not lose output at altitude the way a diesel engine does (a diesel derates significantly as the air thins). The trade is that it needs hydrogen supplied to it, which is why we build it as a hybrid and size the stored hydrogen carefully — but for the posts this exists for, silent, low-signature power is worth engineering the hydrogen logistics around.

Q · 02 How does the hybrid work — why not just a fuel cell?

Because a fuel cell alone is the wrong shape for a real load, and a battery fixes that. A fuel cell is happiest running at a steady output — it responds relatively slowly and is most efficient and long-lived at a constant base load — whereas a real post’s demand is spiky: a radio transmits, a motor starts, a heater cuts in. If you sized the fuel cell to cover every peak, it would be large, expensive and inefficient most of the time. So we hybridise: the fuel cell is sized to the average (base) load and quietly keeps a battery charged; the battery instantly absorbs the peaks and transients; and when demand falls very low — a night-time silent watch — the fuel cell can shut off entirely and the battery carries the post in total silence until the fuel cell restarts to recharge. An energy-management controller runs all of this automatically, and can also fold in solar or an existing diesel generator as extra sources, deciding moment to moment what should supply the load. The result is smaller, cheaper, more efficient and more silent than either a fuel cell or a generator on its own.

Q · 03 Where does the hydrogen come from?

It is supplied to the post, not made there — and that is a deliberate design choice that makes this a deployable power source rather than a plant. The hydrogen arrives as compressed-gas cylinders or, for some applications, in metal-hydride canisters (which store hydrogen at lower pressure, absorbed into a metal), and the system stores and regulates it down to the fuel cell. We size the quantity of hydrogen stored on site to the required runtime and the resupply interval, exactly as you would size a fuel tank — so many cylinders for so many days at the expected load. This is the key difference from a self-contained hydrogen plant: here we are not generating hydrogen on site, we are using it efficiently as a clean, silent fuel that is brought in. (Where a post has spare renewable power and wants to make and store its own hydrogen for round-trip energy storage, that is a different product — our stationary power-to-power system — see the next question.)

Q · 04 How is this different from your hydrogen power-to-power (P2P) system?

They share a fuel cell, but they do opposite jobs, so we keep them as separate products. Our power-to-power (P2P) system is stationary energy storage: it takes surplus electricity (typically from solar or wind), runs an electrolyser to make its own hydrogen, stores that hydrogen, and later runs it back through a fuel cell to give the power back — a round trip that firms a renewable supply on a fixed site, with SCADA and grid-style controls. This fuel-cell hybrid power system is the opposite end: a deployable tactical power source that does not make its own hydrogen — the hydrogen is supplied — and whose whole point is to be rugged, transportable and silent for a forward post, with a battery hybrid for load-following and silent watch. In short: P2P stores energy by making hydrogen; this delivers silent power by consuming supplied hydrogen. Different job, different scale, different platform — and both draw on the same fuel-cell and controls engineering, which is why we can build either.

Q · 05 Do you make the fuel-cell stack?

No — the fuel-cell stack itself and the battery cells are bought-in specialist items, and we are clear about that. The stack (the assembly of membranes and bipolar plates where the electrochemistry happens) is a precision product from established fuel-cell makers, chosen for the power, efficiency and life your duty needs; the battery cells likewise. What Neometrix engineers, integrates and delivers is the complete system around them: the fuel-cell balance-of-plant (air supply, cooling, humidification and hydrogen regulation), the hydrogen storage, the battery bank and DC bus, the power electronics (DC-DC and inverter to 230 VAC / DC), the energy-management controller, and the rugged deployable enclosure with its thermal management — plus installation and commissioning. That is the same integration model as the rest of our hydrogen line, and it plays to strength: the stack is best sourced from the specialists who make stacks, while the system that turns it into silent, deployable field power is our engineering. To be plain about status: this is offered engineered-to-order and quoted against fuel-cell hybrid power requirements; no specific delivered system is claimed on this page.

Q · 06 How does it relate to the rest of your hydrogen products?

It is the using-end of a hydrogen line we already build end to end, which is why it is a natural product for us rather than a leap. Across the range: our green-hydrogen generation plant makes hydrogen; our refuelling and gas-boosting stations compress and dispense it; our power-to-power system stores it and turns it back into electricity on a fixed site; and our electrolyser test station proves the stacks that make it. This fuel-cell hybrid power system sits at the point of use: it consumes supplied hydrogen to deliver silent, deployable electricity where it is needed. So the same company that can make, move, store and test hydrogen also builds the thing that turns it into field power — and because we built our power-to-power system around a fuel cell, storage and controls, the core of this is engineering we have already done, now ruggedised, hybridised with a battery, and pointed at the forward post. It also pairs directly with our field shelters and command posts, which are exactly the kind of load this is built to power silently.
