    摘要： Each of collectors 22 of an electrode structure 20, which partially constitutes a polymer electrolyte fuel cell, is formed from a metal lath MR having a large number of through-holes. A stopping portion 22a in which the through-holes are reduced in diameter is formed at a peripheral end portion of the collector 22. The peripheral end portion of the collector 22 is folded; subsequently, the folded peripheral end portion is pressed, thereby forming the stopping portion 22a. A resin seal portion 23 for sealing introduced fuel gas and oxidizer gas is formed integrally with the stopping portions 22a by insert molding which is performed such that an injected molten resin encloses the stopping portions 22a. The resin seal portion 23 formed integrally with the stopping portions 22a can reliably prevent inflow of the molten resin toward central portions of the collectors 22.

    摘要： There is provided a fuel cell having a seal structure that has high gas sealability and, further, is capable of supplying gas to a membrane electrode assembly without being path-cut even if there are conventional processing errors (variations) in the gasket. With respect to a gasket 5 provided at the periphery of the membrane electrode assembly, a first seal protrusion 51 is formed around a manifold 6. A notch 31 is formed at an end portion of a gas flow path layer 3. An end portion of the gasket 5 blocks the notch 31 and has at least one second seal protrusion 52 protruding from the surface of the gas flow path layer 3 and having a height of the same level as or less than the first seal protrusion 51. A separator 4 is in contact with the gas flow path layer 3 in a posture where the first seal protrusion 51 and the second seal protrusion 52 are compressed. At least one linear seal structure is formed by the second seal protrusion 52 and the separator 4.

    摘要： The deformation of a plate-like member (a separator) or the degradation of a seal function due to heat generated during power generation is suppressed. To realize this, disclosed is a heat insulation cell for a fuel cell in which an insulation layer is constituted of one or more plate-like members and a seal member, the heat insulation cell being provided with a communication section which is disposed in at least a part of a seal line formed by the seal member to seal the insulation layer and the outside of the cell and which connects the insulation layer to the outside. A portion provided with the communication section in at least one of the plate-like members preferably has a projection. It is also preferable that the insulation layer is formed by an insulation member and that the insulation member is disposed in the communication section.

    摘要： A fuel cell diagnostic apparatus that diagnoses a fuel cell in which a plurality of power generating cells are stacked together includes a voltage applying device that applies voltage from outside of the fuel cell; a magnetic field measuring device that measures a magnetic field in or around the fuel cell when external voltage is being applied; and a diagnostic device that diagnoses the state of the fuel cell from the measurement results of the magnetic field. By diagnosing an in-plane distribution of current in the power generating cells by measuring the magnetic field, the distribution of water in an electrolyte membrane after power is generated can be diagnosed based on the diagnostic results of that in-plane distribution of the current.
