Abstract
A fuel cell electricity generation unit including a single cell; first and second interconnectors; a separator; a metal frame member disposed between the separator and the first interconnector; and a gas sealing member having a contact portion in contact with the surfaces of the separator and the second interconnector. The unit has a contact overlap region overlapping with the contact portion in a first direction, and each of the gas sealing member, the separator, the frame member, the first interconnector, and the second interconnector is present in the contact overlap region. At least one of a first weld portion sealing between the separator and the frame member and a second weld portion sealing between the frame member and the first interconnector is formed at a position whose distance from the periphery of the single cell is greater than the distance between the periphery and the contact overlap region.
