Overview

A hydrogen car carries its fuel at 700 bar. Every valve and seal has to be proven.

Hydrogen vehicle fuel systems run at pressures up to 700 bar, across a band from a −40 °C pre-cooled fill to a +120 °C engine bay, with the smallest molecule there is trying to leak past every seal. Before any of those components can be type-approved, each one must be shown to survive its whole service life — and the failure modes that matter — under test. That proof is what this system produces.

Representative render — a hydrogen component test station: a brass and stainless pressure regulator clamped in a heavy high-pressure test fixture, connected by braided stainless high-pressure tubing with compression fittings and a manifold of valves and pressure gauges, light frost on the cold fittings

Fig · 02 A component under test — a regulator on a high-pressure test fixture (representative render)

The system exercises fifteen families of component — pressure regulators, check and cylinder valves, automatic valves, gas injectors, pressure-relief and thermally-activated pressure-relief devices (PRDs and TPRDs), excess-flow valves, filters, rigid and flexible fuel lines, fittings and fuel-cell-vehicle components — through eleven protocols drawn from ISO 12619, UN-ECE R134 and AIS-157.

Those protocols are the service life, compressed: continued-operation cycling to tens of thousands of actuations, hydrostatic-strength and burst testing to twice working pressure, external-leak measurement from −40 to +120 °C, pressure-impulse pulsing, pre-cooled-hydrogen fuelling, permeability, accelerated life and stress-corrosion. Hydrogen is the working fluid where the standard demands it; an inert gas stands in for the destructive strength tests.

Type-approval is not a document — it is a component that has already survived everything the road will do to it. This system is where that happens.

Under Contract · Hydrogen Mobility

Built to the standard

Engineered for a national heavy-engineering enterprise’s hydrogen-component qualification programme; the design is approved and the acceptance-test procedure prepared, with the full protocol suite of ISO 12619, UN-ECE R134 and AIS-157 in scope.

Fifteen Families · Eleven Protocols

One rig, the whole fuel system

Regulators, valves, injectors, TPRDs, lines, filters and fittings — the complete hydrogen fuel-system component set — tested for strength, leak-tightness, endurance and permeability on a single instrumented platform.

Unmanned · Fail-Safe

Hazardous testing, run remotely

High-pressure hydrogen runs are conducted in an ATEX-zoned sealed cell under PLC/SCADA control, with hydrogen gas detection, forced ventilation and fail-safe isolation — the operator behind an armoured window, never beside the pressure.

Architecture

From gas source to type-approval, one instrumented path.

The schematic below is the whole test flow — gas supply, high-pressure boosting, thermal conditioning, the sealed high-pressure cell where the component is exercised, the protocol modules, hydrogen-leak detection, and unmanned SCADA control.

Fig · 03 One test path — gas source and high-pressure booster, thermal conditioning, the ATEX-sealed cell with burst, leak, impulse, cycle and permeability protocols, hydrogen detection and unmanned control

Arc · 01

Pressure & Thermal Conditioning

High-pressure gas boosters raise supply to the burst and impulse pressures the standards demand — into the 700 bar class and beyond for strength tests — while environmental chambers hold the component anywhere from a −40 °C pre-cooled fill to +120 °C. Pressure and temperature are the two axes every hydrogen-component protocol is run across.

Arc · 02

The Sealed Test Cell

Components under high-pressure hydrogen are exercised inside an ATEX-zoned, sealed and ventilated high-pressure cell. Hydrogen gas detection, forced ventilation, fail-safe isolation and remote vent/purge make the cell safe to run unmanned — the energy of a 700 bar hydrogen failure stays behind the barrier.

Arc · 03

The Protocol Suite

Eleven protocols cover the failure modes that matter: continued-operation cycling (to ~50,000 cycles), hydrostatic-strength and burst (2× WP), external leak (−40 to +120 °C), pressure impulse, pre-cooled-hydrogen exposure, pneumatic strength, permeability, accelerated life, injector durability and thermal testing, extreme-temperature pressure cycling and stress-corrosion cracking.

Arc · 04

Measurement & Control

A PLC/SCADA system runs programmed cycle profiles, logs every pressure, temperature and leak channel, and holds the acceptance criteria — outlet-pressure stability, leak-rate limits, no rupture, crack or permanent deformation. High-sensitivity hydrogen/helium detection resolves the small leak and permeation rates the standards set.

The parameters below reflect the system under contract for a national heavy-engineering enterprise. Component set, pressure and temperature ranges and instrumentation are re-scoped against your specification and the standards you certify to.

The cell, its controls & its data

The system is organised around the sealed high-pressure cell and its control room. Gas boosting, thermal conditioning and the protocol modules feed the component under test; the operator runs the campaign from behind an armoured window, with the whole cell interlocked to hydrogen detection and ventilation.

Every channel is instrumented and logged — pressures across the full range, chamber temperatures, actuation counts, and the leak and permeation rates that decide pass or fail. Programmed cycle profiles run the long endurance protocols unattended, to the acceptance criteria written into ISO 12619, UN-ECE R134 and AIS-157.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 What exactly does this system qualify?

Components, not whole vehicles. It type-qualifies the individual parts of a hydrogen vehicle’s fuel system — the regulators, check and cylinder valves, automatic valves, gas injectors, pressure-relief and thermally-activated relief devices (PRDs and TPRDs), excess-flow valves, filters, rigid and flexible fuel lines, fittings and fuel-cell-vehicle components. Fifteen families in all. Each has to be shown to meet the requirements of ISO 12619, UN-ECE R134 and AIS-157 before it can go into a type-approved fuel system, and this rig runs the full set of tests those standards call for.

Q · 02 Why test to twice the working pressure?

Because a safety-critical pressure component must have a large margin over the pressure it will ever see in service. A 700 bar-class component works at 700 bar, but the standards require it to survive a hydrostatic-strength or burst test at roughly twice that without rupture, crack or permanent deformation. Proving the margin — not just the rating — is what separates a type-approved component from an untested one, and it is why the system carries high-pressure gas boosters.

Q · 03 How is hydrogen tested safely at these pressures?

The high-pressure hydrogen runs happen inside an ATEX-zoned, sealed and ventilated test cell, with the component behind an armoured barrier and the operator in a separate control room. The cell is interlocked to hydrogen gas detection and forced ventilation, with fail-safe isolation and remote vent and purge, and the long protocols run unmanned under SCADA control. Where a test only needs to prove mechanical strength, an inert gas is used in place of hydrogen to remove the flammability risk entirely.

Q · 04 What is the temperature range, and why the pre-cooled fill?

Components are tested from around −40 °C to +120 °C — the band a fuel component actually lives in, from a cold climate and the −40 °C pre-cooled hydrogen used for fast fills, up to the heat of an engine bay. The pre-cooled-hydrogen exposure test follows the UN-ECE R134 fuelling protocol, because filling a 700 bar tank quickly cools the incoming gas sharply, and every component near the fill path has to keep sealing through that thermal shock.

Q · 05 Which standards does it work to?

The three that govern hydrogen vehicle fuel-system components: ISO 12619 (Parts 3–16, the component-specific requirements), UN-ECE Regulation 134 (the international type-approval regulation for hydrogen and fuel-cell vehicles and their components), and AIS-157 (the Indian automotive standard for hydrogen fuel-cell vehicles). The test protocols, pressures, temperatures and acceptance criteria on this system are drawn directly from those documents.

Q · 06 Can you build to our components and standards?

Yes — this is a build-to-specification system. Tell us the component families you make, the service pressure classes (350, 700 bar or other), the temperature range, the media and the standards you certify to, and the system is scoped to match — cell, boosters, chambers, protocol modules, instrumentation and SCADA.
