Platinum Dissolution During Fuel Cell Operation

Per on J, Nedellec Y, Jones D J and Rozidre J (2008), The effect of dissolution, migration and precipitation of platinum in Nafion-based membrane electrode assemblies during fuel cell operation at high potential ,/Power Sources, 185,1209-1217... [Pg.600]

One critical issue facing the commercialization of low-temperature fuel cells is the gradual decline in performance during operation, mainly caused by the loss of the electrochemical surface area (EGA) of carbon-supported platinum nanoparticles at the cathode. The major reasons for the degradation of the cathodic catalyst layer are the dissolution of platinum and the corrosion of carbon under certain operating conditions, especially those of potential cycling. Cycling places various loads on... [Pg.121]
