Abstract

Provided is a fuel-cell unit cell having a first gas diffusion layer that is laid on a first surface of a membrane-electrode assembly such that an outer peripheral edge portion thereof protrudes from the first surface of the membrane-electrode assembly. At a first part of the fuel-cell unit cell: the fuel-cell unit cell has a bonding layer; between the membrane-electrode assembly and a portion of the first gas diffusion layer on an inner side from the outer peripheral edge portion thereof, the bonding layer bonds the membrane-electrode assembly and the portion together; and between a support frame and the outer peripheral edge portion of the first gas diffusion layer, between the support frame and a first separator, and/or between the support frame and a second separator, the bonding layer bonds the support frame and the outer peripheral edge portion or the separator together.
