  • Patent number: 9105936
    Abstract: A fuel cell catalyst includes a platinum-iron (Pt—Fe) alloy having an ordered or disordered face-centered cubic structure or face-centered tetragonal structure. The face-centered cubic structure has a lattice constant ranging from about 3.820 ? to about 3.899 ? (or from about 3.862 ? to about 3.880 ?), and the face-centered tetragonal structure has a first lattice constant ranging from about 3.800 ? to about 3.880 ? (or from about 3.810 ? to about 3.870 ?) and a second lattice constant ranging from about 3.700 ? to about 3.810 ? (or from about 3.710 ? to about 3.800 ?). A membrane-electrode assembly can improve cell performance by including the above catalyst having the relatively high activity and selectivity for an oxidant reduction in at least one of an anode or a cathode, and can increase lifespan by inhibiting catalyst poisoning.
