ABSTRACT:
A fuel cell has an anode, a cathode, and a polymer electrolyte membrane placed between the anode and the cathode. The anode includes a catalyst which is composed of binary or ternary particulates deposited on a carbon support. The particulate is represented by a general formula: Pt—P, wherein Ru is optionally present. The content of P is in a range of 2 mol % to 50 mol % based on the total moles of Pt or Pt—Ru. The diameter of the catalyst particulates is in range from 1 to 3 nm.
