Testing one fuel cell or electrolyzer often means testing several different gases, hydrogen, oxygen, air, helium, and custom blends, without room in the lab for a separate instrument dedicated to each one. Greenlight Innovation builds test stands used from single-cell chemistry validation up through full stack verification. Their customers needed data accurate enough to qualify a technology headed for commercialization, and the flexibility to switch gases mid-session without swapping hardware. Alicat mass flow controllers and meters let Greenlight's customers change gas calibration with the click of a button, while a turndown ratio up to 10,000:1 keeps readings accurate even as flow rates shift with the gas change. ATEX Zone 0, 1, or 2 and C1D1 or C1D2 certified options are available where hydrogen throughput calls for it. The result is fewer instruments per test stand and one certification strategy that works across every rig. ⬇️More details about this application in the comments.

Continuous hydrogenation runs at steady state, so small shifts in H2 flow or pressure can affect stoichiometry, catalyst performance, and the reliability of online measurements. In this 4-minute read, see how one integrator approached hydrogen flow control in a Class I, Division 1 environment without relying on an inefficient N2 purge-box setup. With intrinsically safe IS-Max flow control, engineers can bring accurate, responsive hydrogen dosing directly into the hazardous zone while tracking more process data from a single instrument. If your process depends on precise hydrogen dosing, catalyst performance, or online analytics, this case study is worth a closer look.

See how engineers for leading fuel cell and electrolysis test stand manufacturers are helping to bring hydrogen energy to scale by using more flexible, data-rich gas flow and pressure controllers. They take advantage of 0.5 sccm to 12,000 SLPM full scale flows, setpoints that stabilize in 30 milliseconds, and field changeable gas selections to iterate their experiments, keep inventory low, and proton-exchange membrane testing going.

What do these fuel cell testing engineers know that you don’t? • How RH sensors in MFCs can make electrolysis efficiency measurements more accurate, and fuel cell gas feeds more predictive of stoic • Where to find intrinsically safe gas and pressure instruments for explosive-gas hazard zones • What it means to get up to 13 parameters of data about the conditions and stoic in their test stand, from a single MFC • Why flow controllers with field-selectable gas calibrations and turndown ratios up to 10,000:1 make their systems more flexible and reduce component inventories

Fuel cell test engineers use fast, stable control of gas flow, back pressure, temperature, and humidification to generate reliable performance data and scale test conditions with confidence. Alicat supports hydrogen fuel cell regulation and testing with flow and pressure instruments designed for diagnosis, system optimization, and easier integration into test software. That includes differential pressure mass flow controllers that monitor both pressure and mass flow simultaneously, <50 ms response times for stable temperature regulation, 10,000:1 turndown ratios for scaling through development, dual-valve pressure controllers that reach setpoints in milliseconds without continuous bleeding, and stainless steel DP mass flow meters that provide accurate readings even when moisture passes through the unit. See how teams in hydrogen fuel cell testing are using better flow verification, richer system insight, and easier software integration to improve validation and development.
