Single-cell PEM electrolysers for small-scale hydrogen production in mild conditions were designed, built and tested at 40ºC and 6.9barg H2 differential pressure. The effect of membrane material, catalyst loading, and clamping pressure was studied for different cells, with the use of i-V curves, impedance spectroscopy, and gas crossover estimation. It was found that membrane selection and clamping pressure applied through bolt loading was more important than the effect of catalyst loading in either anode or cathode for cell performance, under the studied conditions.
