Abstract

Conventional PEFC electrocatalysts have a difficulty in durability against start-stop potential cycling, mainly.due to degradation of carbon black, supporting Pt nanoparticles, through electrochemical oxidation especially on the cathode side. SnCh support has high electronic conductivity among various oxide supports, and is stable under the strongly acidic PEFC cathode condition. In this study, freeze drying has been successfully applied as an effective procedure for highly dispersing SnCh nanoparticles on conductive framework, for nanostructuring PEFC electrocatalysts.
