    摘要： A method of starting operation of a fuel cell stack includes the steps of performing gas replacement by supplying a fuel gas to a fuel gas flow field from a downstream side of the fuel gas flow field through a fuel gas discharge passage, and supplying an oxygen-containing gas to an oxygen-containing gas flow field from an upstream side of the oxygen-containing gas flow field through an oxygen-containing gas supply passage. After the step of performing gas replacement, normal power generation is carried out by supplying the fuel gas to the fuel gas flow field from an upstream side of the fuel gas flow field through a fuel gas supply passage, and supplying the oxygen-containing gas to the oxygen-containing gas flow field from the upstream side of the oxygen-containing gas flow field through the oxygen-containing gas supply passage.

    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： 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.
