摘要： A fuel cell module, wherein slopes of a same angle θ relative to a bottom face are formed on both side faces to form a recessed groove in a tapered shape. Since the angle θ is provided to the side faces of the recessed groove, the exhaustion of gases from the accumulation of gasses to the outside can be assisted by the side faces with the angle θ more than in a case where the side faces of the recessed groove are formed in right angled shapes even if the accumulation of gases is produced between an adhesive agent and the inner surfaces of the recessed groove when first and second separators are joined to each other for modularization by covering the first separator on the second separator. Thus, the accumulation of the gases can be prevented from occurring.

摘要： A fuel-cell stack is provided wherein an insulating resin layer having good electrical insulation characteristics is inserted between a terminal and end plate, so that an insulating plate is discarded so as to make the same more lightweight and downsized. It comprises a battery-cell group wherein a plurality of battery cells and separators are arranged; and terminal plates 1 and end plates 3 that are arranged on each end portion of the battery-cell group. The end plates 3 are formed as metal plate members having surfaces 31 opposing to the terminal plates 1. A polyimide film 35 is formed as an insulating resin layer at least on the opposing surface 31 of the end plate 3 for electrically insulating between the end plate 3 and terminal plate 1 by an electro-deposition coating method.

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.
