Abstract
AbstractProton exchange membrane fuel cells (PEMFCs) have attracted significant interest as one of the most promising green energy technologies. However, the stability of platinum‐based catalyst layer at the cathode hinders the large‐scale application of the PEMFCs. This review systematically summarized the latest research progress on the stability of catalyst layer from the stability of nanoparticles, corrosion resistance of carbon support, chemical stability of ionomer and weakened toxic effect of ionomer on platinum particles. Strategies to enhance the stability of the catalyst layer were discussed as well, including increasing the dissolution potential of the nanoparticles, enhancing the metal–support interaction, modifying the structure and composition of the carbon support, and improving the distribution of the ionomer. This review aims to provide a comprehensive overview of the stability of cathode catalyst layer, serving as a reference for the design of catalyst layer with stability in the future.
