Research Abstract

New Pt single-atom electrocatalyst was investigated to reduce the amount used of Pt for polymer electrolyte fuel cells. As a result, (i) Low Pt loading electrode was successfully prepared only 0.6 wt% Pt. (ii) Onset potential of hydrogen oxidation reaction at obtained Pt electrode as large as that at Pt plate as a reference.
