 note = {application/pdf, Degradation of a carbon-supported Pt (Pt/C) catalyst used at the cathode of polymer electrolyte fuel cells was investigated. The Pt/C sample was prepared by the polygonal barrel-sputtering method. The results showed that the Pt nanoparticles were highly dispersed on the powder carbon support. The cyclic voltammograms of the prepared Pt/C sample showed that the Pt particles were electrochemically cleaned by 100 repetitions of the potential cycling. Further continuation of potential cycling, however, resulted in the gradual decrease in H adsorption/desorption currents, indicating a loss of the electrochemical surface area (ESA) of the deposited Pt. Note that the ESA obtained after the 4000th potential cycling was ca. 20% of that at 1st potential cycling, and the decrease in the ESA is most likely attributed to the growth and aggregation of the deposited Pt particles., Article, 富山大学水素同位体科学研究センター研究報告, 32巻, 2013.05.31, pp.21-26},
