More Information
Summary:A catalyst for a membrane electron assembly (MEA) comprising: a ternary oxide material having at least one composition of formula (I): IrxM1-xO2 (I), where x is any number between about 0.25 and 0.75, and M is Ag, Au, Ba, Bi, Ca, Ce, Eu, Ge, Hf, La, Nd, Os, Pd, Pr, Re, Rh, Se, Sm, Tl, or W, the material being configured to catalyze oxygen evolution reaction (OER) and increase stability, activity, or both of the catalyst.
