Front Cover: Performance‐Conscious Coadditive Approach for Enhancing Proton Exchange Membrane Durability: Roles of Tungsten Oxides and Cerium Ions (ChemElectroChem 19/2025)

Year: 2025

Type: paratext

Abstract: Hydrogen peroxide is decomposed by tungsten oxide within the water domains of a proton exchange membrane in a fuel cell, while cerium ions quench aggressive hydroxyl radicals that arise from the reaction between hydrogen peroxide and ferrous ions. The illustration contrasts the roles of the two additives: cerium protects but slows proton transport, whereas tungsten oxide prevents degradation without hindrance. Together they represent a balanced strategy that prevents membrane degradation while maintaining high fuel cell performance.
