Effect of Catalyst and Catalyst Layer Composition on Catalyst Support Durability

open access: yesJournal of The Electrochemical Society, 2021
Polymer electrolyte membrane fuel cells (PEMFCs) are efficient, zero-emission engines for the automotive sector. However, cost and durability are major barriers for the commercialization of PEMFCs. Degradation of the carbon support in the cathode catalyst layer due to high potential excursions caused by unmitigated events like H2 starvation, or start ...
