ABSTRACT:
The catalyst of this invention is a non-stoichiometric tungsten compound, H0.53WO3, which may be used as both the anode and cathode electrocatalyst for acid-style low-temperature fuel cells. A fuel cell using the tungsten-based electrocatalyst as both the anode and cathode has been constructed and operated with a hydrogen fuel and an air oxidant.
