The Stability of Platinum–Carbon Aerogel Catalysts upon Repeated Potential Cycles

Authors


Abstract

A sense of stability: The stability of carbon-supported platinum catalysts at high potentials is important for the commercialization of fuel cells for homes and cars. The electrochemical active surface (EAS) area of a Pt–C aerogel catalyst was found to increase up to 500 cycles, in contrast to that for the so-called Tanaka catalyst which decreases with the number of repeated potential cycles.
