| Outline of Final Research Achievements |
In order to investigate the ideal reaction environment (site) for increasing the durability of polymer electrolyte fuel cells (PEFCs), ①synthesis of electrocatalysts based on nanostructurally controlled carbon, ②analysis of electronic and ionic conductivity of the electrocatalysts, ③development of fuel cell devices and evaluation of their performance, and ④application to other hydrogen related devices were considered. As a result, carbon with nanochannels of 10 nm diameter was successfully developed. With this carbon material, mobility of Pt nanoparticles introduced into the pores was suppressed, resulting in higher durability of PEFC. Effective pore structure was confirmed for increasing durability of PEFC.
