    摘要: A fuel cell system having improved driving performance is disclosed. The fuel cell system includes a stack, which may include a membrane electrode assembly, a separator and end plates provided on the both sides of the stacked membrane electrode assembly and the separator. The membrane electrode assembly may include an anode electrode, a cathode electrode, and an electrolyte membrane. The separator may be positioned with respect to the anode electrode and the cathode electrode, respectively. The end plate may include an oxidant inlet configured to supply oxidant to the cathode electrode, an unreacted oxidant outlet configured to output the unreacted oxidant from the cathode electrode, and a absorption member in fluid communication between the oxidant inlet and the unreacted oxidant outlet.

    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.
