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 (60); between a first separator (30) and an outer peripheral edge portion (22a) of a first gas diffusion layer (22), the bonding layer (60) bonds the first separator (30) and the outer peripheral edge portion (22a) together; between the first separator (30) and an outer peripheral edge portion (21a) of a membrane-electrode assembly (21), the bonding layer (60) is bonded to the outer peripheral edge portion (21a) of the membrane-electrode assembly (21); and between the first separator (30) and a support frame (50) and/or between a second separator (40) and the support frame (50), the bonding layer (60) bonds the support frame (50) and the separator (30, 40) together.
