Complex cobalt oxide catalysts for oxygen reduction electrodes in alkaline fuel cells
Oxygen is reduced in the presence of a catalyst at the cathode of an alkaline-electrolyte fuel cell. Catalysts of the formula Sr3−xA1+xCo4−yByO10.5−z wherein −0.6≦x≦1.0; 0≦y≦3; and −1.5≦z≦0.5; wherein A represents Eu, Gd, Tb, Dy, Ho, or Y; and wherein B represents Fe, Ga, Cu, Ni, Mn, and Cr, demonstrate high catalytic activity and high chemical stability when used as the oxygen-reduction catalyst in alkaline fuel cells.
