Fuel cell performance and durability
PEM and solid oxide fuel cell behaviour under realistic load profiles, humidity and temperature.
Fuel cells and conversion
Fuel cell and electrochemical conversion engineering.
Support where selectivity, interfaces, durability and operating windows decide whether a conversion concept is genuinely usable.
What we look at
Where conversion concepts succeed or stall.
Catalyst layers and electrodes
Platinum-group-metal loading, ionomer distribution and electrode structure.
CO₂ and nitrogen electroreduction
Faradaic efficiency, product selectivity and stability beyond short laboratory runs.
Electrosynthesis routes
Electrochemical production of chemicals and fuels, and what limits scale-up.
Gas diffusion electrodes
Water and gas management, including flooding, which often decides lifetime in conversion cells.
Operating window and system fit
Current density, temperature and feed purity requirements versus what a real plant can provide.
Typical questions
Questions teams bring to us
- Is selectivity stable over realistic run times?
- Which interface or catalyst layer limits durability?
- Is the operating window practical outside the lab?
How evidence is built
Methods we design test plans around and interpret
Selectivity and mass-balance checks
Confirming that reported product yields close the carbon or nitrogen balance.
Long-duration stability testing
Run times and conditions long enough to reveal drift rather than initial performance.
Impedance and polarisation analysis
Identifying which electrode or interface limits performance.
Techno-economic sensitivity
Showing which performance metric moves the cost case most.
Frequently asked questions
Does Redionix work on fuel cells as well as electrolysers?
Yes. PEM and solid oxide fuel cells share many materials and failure questions with electrolysers, and the same evidence-first approach applies to both.
How do you assess a CO₂ electroreduction result?
By checking selectivity and current density together, confirming the carbon balance, and asking whether stability has been shown over a realistic duration rather than a short demonstration.
Can you help decide between conversion routes?
Yes. A route comparison sets technical maturity, the key performance gaps and the evidence still needed side by side, so the decision rests on more than headline numbers.
Working on something in this area?
Describe the system, the decision and the evidence you already have. That is enough for a useful first conversation.
