Research Institution
Degradation of the cathode catalyst has been identified as one of the major challenges to achieving the cost and performance targets for Proton Exchange Membrane fuel cells (PEMFCs), for both automotive and stationary power applications. The degradation is manifested in the forms of detachment, agglomeration of particles, Ostwald ripening of particles, migration of Pt away from the cathode, and the precipitation of Pt within the membrane. Recent work has shown that the principal factor governing the degradation of PEMFC cathode is Pt ion concentration. Therefore, this project will develop novel cathode catalysts that not only are highly active but also are degradation-resistant and maintain their activity by suppressing Pt dissolution. Commercial Applications and other Benefits as described by the awardee: The low cost, degradation-resistant PEMFC cathode catalysts should enable the commercial viability of PEMFC for both automotive and stationary power applications.
