摘要： A fuel cell stack includes a first power generation unit and a second power generation unit. Wave-like first fuel gas flow passages of the first power generation unit and wave-like first fuel gas flow passages of the second power generation unit are set to mutually different phases. The ends of the first fuel gas flow passages form linear flow passage grooves that linearly extend in the wavelength direction from the center of the width of the wave-form amplitude.

摘要： A fuel cell includes an electrolyte-electrode assembly, a frame member, a first separator, and a second separator. The frame member is provided to face a first surface of the second separator and includes a resin wall which forms a periphery of a first reactant gas passage. The resin wall has a thin-walled portion which overlaps with a cooling medium connecting portion in a stacking direction and which protrudes toward the first reactant gas passage in the stacking direction by a first dimension from a surface of the frame member. Another portion of the resin wall protrudes toward the second separator in the stacking direction by a second dimension from the surface of the frame member. The first dimension is smaller than the second dimension.

摘要： A fuel cell system includes a plurality of fuel cell stacks, an anode pipeline, a cathode pipeline, an anode discharge valve, a cathode supply valve, a cathode discharge valve, an anode pressure sensor, a cathode pressure sensor, and a control device. The control device determines whether a cross leak that is permeation abnormality of fuel gas or oxidant gas between an anode and a cathode on the basis of a pressure difference, which is difference between a pressure of the fuel gas and a pressure of the oxidant gas detected by the anode pressure sensor and the cathode pressure sensor in a stopped state of electric power generation of the plurality of fuel cell stacks, or a change in the pressure difference.

摘要： A plurality of anode wavy portions provided in an anode separator of a fuel cell have wavy patterns in the same phase, and are arranged in an amplitude direction of the anode wavy portions at a first pitch. A plurality of cathode wavy portions provided in a cathode separator have wavy patterns in the same phase but in reverse phase with respect to the anode wavy portions, and are arranged in an amplitude direction of the cathode wavy portions at a second pitch. The first pitch and the second pitch have different sizes.

摘要： A membrane electrode assembly with protective film includes a MEA and protective films. The MEA includes a cathode, an anode, and a solid polymer electrolyte membrane interposed between the cathode and the anode. The protective films are joined on the outer end of the solid polymer electrolyte membrane. The membrane electrode assembly has a power generation area and an edge-vicinity area. Recesses for receiving the edge-vicinity area including outer ends of the cathode and the anode are formed in outer portions of a cathode-side separator and an anode-side separator which contact the MEA.

摘要： A fuel cell stack comprising a second metal separator set to have an external dimension larger than a first metal separator, wherein the second metal separator comprises, formed integrally, a first seal member in contact with the peripheral edge of a first electrolyte membrane/electrode structure, a second seal member in contact with the peripheral edge of the first metal separator, and a third seal member in contact with the peripheral edge of an adjoining fourth metal separator. Since the first seal member, the second seal member and the third seal member are integrally formed on one surface of the second separator or one surface of the first separator, a seal-forming step can be carried out at one effort, simply and economically. In addition, use of a triple seal structure containing the first through the third seal members can favorably improve the sealing feature of reaction gas and minimize reaction gas leakage.
