Abstract:
An oxygen electrode comprising:a porous first layer having a built-in hydrophobic character including an active catalyst material deposited from a precursor selected from a group consisting of AgNO3, a AgNO3/Ga(NO)3 mixture, a AgNO3/LiNO3 mixture, Co(NO3)2, a cobalt amine complex, NI(NO3)2, Mn(NO3)2, cyano complexes, organo-metallic complexes, amino complexes, citrate/tartrate/lactate/oxalate complexes, transition metal complexes, and mixtures thereof; a porous second layer disposed adjacent to said porous first layer having a greater built-in hydrophobic character than said porous first layer; and one or two current collector grids adapted to provide support to said porous first layer and said porous second layer.
