Communication—Pt-Doped Thin Membranes for Gas Crossover Suppression in Polymer Electrolyte Water Electrolysis

Abstract

© The Author(s) 2019. Published by ECS. Hydrogen gas crossover is a major safety issue in polymer electrolyte water electrolyzers (PEWE) and a limiting factor for the use of thinner polymer electrolyte membranes for high voltage efficiency PEWE. This article outlines a simple impregnation method for a recombination catalyst, yielding high crossover suppression for thinner membranes at differential pressures without negative effects on the cell performance.
