    摘要: A fuel cell includes a membrane electrode assembly and an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. An oxygen-containing gas flows in an oxygen-containing gas flow field in a horizontal direction. A coolant flows in a coolant flow field in a vertical direction. The coolant flow field is connected to coolant supply passages and coolant discharge passages. The opening of one of the coolant supply passages and the opening of one of the coolant discharge passages are smaller than those of the other coolant supply passages and the other coolant discharge passages in cross section, respectively. Thus, the flow rate of the coolant supplied to an area near outlets of the oxygen-containing gas flow field and the fuel gas flow field become smaller than the flow rate of the coolant supplied to the other area.

    摘要: A first separator has an outlet side first connection channel connecting a first fuel gas flow field and a fuel gas discharge passage, and a second separator includes an outlet side second connection channel connecting a second fuel gas flow field and the fuel gas discharge passage. The outlet side first connection channel and the outlet side second connection channel include outer passages and outer passages arranged in the same plane formed by facing the first separator and the second separator. The outer passages and the outer passages are formed alternately and independently in the same plane.

    摘要: An oxygen-containing gas supply passage and an oxygen-containing gas discharge passage extend through a set of diagonal positions of a first metal separator, and a fuel gas supply passage and a fuel gas discharge passage extend through the other set of diagonal positions of the first metal separator. A fuel gas flow field is connected to the fuel gas supply passage through an inlet buffer at an upper position, and connected to the fuel gas discharge passage through an outlet buffer at a lower position. The inlet buffer includes a first inlet buffer area adjacent to the fuel gas supply passage and a second inlet buffer area adjacent to the fuel gas flow field. Grooves of the first inlet buffer area are deeper than grooves of the second inlet buffer area in the stacking direction.

    摘要: In a first aging step, a plus electrode electric potential is applied to an anode of a fuel cell, and a minus electrode electric potential is applied to a cathode of the fuel cell. In this state, hydrogen pump operation is performed at maximum current density in use by supplying humidified hydrogen to the anode without supplying any oxygen-containing gas to the cathode. Thus, the hydrogen passes through a solid polymer electrolyte membrane toward the cathode. After the first aging step, in a second aging step, power generation of the fuel cell is performed at the maximum current density.
