Hydrogen Energy
Hydrogen fuel cell testing with better data. Safer PEM electrolysis.
For hydrogen fuel cell test stands that prioritize accurate flow verification and rich data reporting, multivariate mass flow instruments from Alicat® exceed the requirement. Get component instruments built to your process specifications. CID1 (or CID2) requirements, and high flow rates are no longer constraints when sourcing a pressure or flow meter for your hydrogen electrolysis, or fuel cell testing skid. Flow up to 12,000 SLPM and can integrate into your testing software.
Use CODA™ Coriolis flow controller and PC series pressure controllers for hydrogen electrolysis
- CODA Coriolis controller measures flow directly as mass with liquid accuracy as good as 0.2% of reading or 0.05% FS
- CODA enables high turndown liquid control (2 – 100% of full scale) at high pressures and wide temperature range (−35° – 70° C)
- PC series controllers can be configured to control backpressure with accuracy as good as ± 0.125% of full scale accuracy and respond quickly (~30 ms) to rapid pressure fluctuations.
- PC Series pressure controller uses integrated PID control to respond quickly (~30 ms) to rapid pressure fluctuations
- Alicat pressure controllers are available in CID2 & intrinsically safe CID1 build options for use in hazardous gas zones.
Mass flow and pressure applications in hydrogen energy
Intrinsically safe mass flow controller for PEM electrolysis
When using hydrogen electrolyzers, the close proximity of hydrogen and oxygen requires continuous monitoring. In a (CID2) hydrogen lab, a PEM electrolyzer was configured with meters to measure hydrogen and oxygen output, warning operators of any cross‑contamination. Using IS‑Max™ lead to faster detection of faults, safer shutdowns, and less risk of dangerous hydrogen‑oxygen mixtures forming.
Gas flow and pressure solutions for fuel cell testing
Alicat mass flow and pressure instruments can be used for hydrogen fuel cell testing, diagnosis, and system regulation. Fast response times and 10,000:1 turndown ratios can ensure stable temperature regulation or back pressure control. Choose from differential pressure mass flow controllers for high flow, or miniaturized Coriolis instruments for high pressures with low flow rates.
