CARBON-SUPPORTED PLATINUM AND METAL OXIDE ELECTROCATALYSTS FOR CO-TOLERANT PEFC ANODE

摘要

Carbon-supported Pt and metal oxide electrocatalysfts for CO-tolerant anode are reported by focusing on some kinds of transition metal oxides (Mo, Ti, W oxides). The cell using Pt/MoO_x/C catalysts showed better CO tolerance than Pt/C in 100 ppm CO/H_2 atmosphere. The terminal voltage of the cell with Pt/MoO_x/C catalyst improved more than 300 mV at 0.5 A cm~(-2) than that of Pt/C.
