Abstract

A new principle for designing catalyst supports with water activation ability was proposed. According to this principle, stabilized nickel(+3) oxides with different dopants were tested as possible support and promoter for Pt catalyst in direct methanol fuel cells. It was found that the chemical and electrochemical stabilities of these novel supports in acidic solution were sufficient. The support doped with Al(+3) has catalytic activity towards methanol electrooxidation while that doped with Co(+3) can improve both activity and poisoning tolerance of the Pt catalyst.
