Elucidating the effect of mass transport resistances on hydrogen crossover and cell performance in PEM water electrolyzers by varying the cathode ionomer content

Trinke, P.; Keeley, G.P.; Carmo, M.; Bensmann, B.; Hanke-Rauschenbach, R. (Bristol : IOP Publishing Ltd., 2019)

An important challenge for polymer electrolyte membrane (PEM) water electrolysis is to reduce the permeation of the produced gases. This crossover affects the cell efficiency and causes safety issues. The crossover increases ...
Hydrogen Crossover in PEM Water Electrolysis at Current Densities up to 10 A cm−2

Martin, Agate; Trinke, Patrick; Bensmann, Boris; Hanke-Rauschenbach, Richard (Bristol : IOP Publishing, 2022)

Hydrogen crossover poses a critical issue in terms of the safe and efficient operation in polymer electrolyte membrane water electrolysis (PEMWE). The impact of key operating parameters such as temperature and pressure on ...
