    摘要: 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 Å to about 3.899 Å (or from about 3.862 Å to about 3.880 Å), and the face-centered tetragonal structure has a first lattice constant ranging from about 3.800 Å to about 3.880 Å (or from about 3.810 Å to about 3.870 Å) and a second lattice constant ranging from about 3.700 Å to about 3.810 Å (or from about 3.710 Å to about 3.800 Å). 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.
