This Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program provides $519,236 to The Research Foundation For The State University Of New York to conduct research aimed at enhancing the performance and durability of platinum-based catalysts used in proton exchange membrane fuel cells (PEMFCs). The primary goal is to improve the oxygen reduction reaction (ORR) catalyst durability by introducing metal dopants and adjusting the atomic arrangement on the platinum-nickel catalyst surface layer. This research seeks to develop more efficient and longer-lasting ORR electrocatalysts, which could significantly enhance green energy conversion processes and benefit both the environment and society. The project involves specialized catalyst design, synthesis, and analysis to understand degradation mechanisms and optimize catalyst functionality. Broader impacts include providing research opportunities for junior researchers and disseminating findings to the public to foster a more sustainable future.
