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.
A fuel cell comprising a membrane electrode assembly that comprises at least an electrolyte membrane and an anode electrode layer and a cathode electrode layer that sandwich it, gas flow path layers that sandwich the membrane electrode assembly, and separators that sandwich the gas flow path layers, and comprising a gasket having a manifold that is formed in the periphery of the membrane electrode assembly and the gas flow path layers and that serves as a gas flow path, wherein,
