FUEL-CELL UNIT CELL

Disclosed herein is a fuel-cell unit cell, at a first part of which: the fuel-cell unit cell has a bonding layer; between an outer peripheral edge portion of a first gas diffusion layer and a portion of a membrane-electrode assembly on an inner side from an outer peripheral edge portion thereof, the bonding layer bonds these portions together; between a first separator and the outer peripheral edge portion of the membrane-electrode assembly, the bonding layer is bonded to at least the outer peripheral edge portion of the membrane-electrode assembly; and between the first separator and a support frame and/or between a second separator and the support frame, the bonding layer bonds these parts together.
