Carbon supported Pt75M25 (M= Co, Ni) alloys as anode and cathode electrocatalysts for direct methanol fuel cells
The behaviour of carbon supported Pt75M25 (M= Co, Ni) electrocatalysts, both as anode
and cathode materials, was investigated in direct methanol fuel cells (DMFCs) and
compared to that of a pure Pt electrocatalyst on the same carbon support. The physical and
morphological characteristics of these electrocatalysts were examined by XRD, XAS and
TEM techniques. The performances of Pt75Ni25/C and Pt75Co25/C as cathode materials in
DMFC were better than those of the same electrocatalysts as anode materials. When used …
