Abstract
A physicochemical model of an intermediate-temperature water (steam) electrolyzer based on a proton exchange membrane (PEM) was developed. The results of numerical modeling provide recommendations for membrane-electrode assembly (MEA) parameters based on the required electrolyzer operating conditions. Specifically, electrocatalytic layer thicknesses can be recommended to ensure high electrolyzer performance with optimal platinum metals content. The importance of sufficient ionomer in the electrocatalytic layers is demonstrated.
