摘要： A first metal separator of one of adjacent power generation cells and a second metal separator of the other of the adjacent power generation cells are directly stacked together to form a coolant flow field. The first metal separator has a press line protruding toward the coolant flow field, between a fuel gas flow field and an inlet buffer. The second metal separator has a press line protruding toward the coolant flow field, between an oxygen-containing gas flow field and an inlet buffer. The press lines contact each other to limit flow of the coolant into a back surface buffer.

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.

摘要： A humidity sensor is disposed in a circulation passage as a passage of a hydrogen gas supplied to an anode of a fuel cell stack. A load current setting unit determines a level of electrical current supplied to a load. A flow rate controller controls a compressor based on the humidity detected by the humidity sensor and the load current determined by the load current setting unit to regulate a flow rate of the air supplied to a cathode of the fuel cell stack for maintaining the humidity of the hydrogen gas within a predetermined range less than 100%. The fuel cell stack generates the load current efficiently without discharging the hydrogen gas to the outside.

摘要： A fuel cell stack having stacked unit fuel cells, each having a pair of separators between which a membrane electrode assembly is provided, which includes an anode and a cathode. Each separator has protruding lines arranged vertically in a zigzag manner, which protrude in a direction going away from the membrane electrode assembly. A space between the anode and the protruding lines of the separator facing the anode is used as a fuel gas passage. A space between the cathode and the protruding lines of the separator facing the cathode is used as an oxidant gas passage. At least part of the separators are each arranged in close contact with another separator so that a coolant passage through which a coolant flows horizontally is formed between both separators. A lower area of the coolant passage has a larger flow resistance than that of an upper area thereof.
