Abstract
NOBLE metals have been found to be the most suitable materials as anode catalysts for hydrogen oxidation in low temperature fuel cells containing an acid electrolyte. The one exception is tungsten carbide1, which is the only compound to have shown catalytic activity and sufficient resistance against corrosion in acid media under anodic polarization to act as an anode catalyst. In addition, tungsten carbide (WC) possesses a good electrical conductivity.
