Effect of catalyst layer microstructures on performance and stability for high temperature polymer electrolyte membrane fuel cells
TL;DR: In this paper, the effect of Pt loading on the performance and degradation of high temperature polymer electrolyte membrane fuel cells (HT-PEMFCs) was studied and the results revealed that mass transfer is affected greatly by the effects of microstructures and Pt loadings, and gets deterioration gradually with the invasion of PA into CLs, which not only makes Pt particle growth but decreases kinetics of oxygen reduction reaction.
