Currently, the low activity, poor durability, and high cost of the cathode catalysts in Proton Exchange Membrane fuel cells and Direct Methanol fuel cells constitute some of the major barriers to the commercialization of fuel cells. In particular, the durability of Pt-based catalysts can be compromised by sintering and dissolution, especially at high electrode potentials or under load-cycling. This project will nano-engineer multi-metallic-alloy nanoparticle catalysts with a combination of properties that will enhance activity, optimize stability, and reduce cost. Phase I work will demonstrate the feasibility of scaling-up a patented process for the production of low-cost, active, and robust catalysts for the fuel cell market.
Commercial Applications and Other Benefits as described by the awardee: The new catalysts should enable the widespread commercialization of fuel cells. The catalyst is one of the key fuel cell components, currently accounting for ~30% of the cost of manufacturing fuel cells
