PROBLEM TO BE SOLVED: To provide a solid polymer electrolyte fuel cell integrally containing a humidifying part for reaction gas. SOLUTION: A unit fuel cell (unit cell) 2 possessed by this solid polymer electrolyte fuel cell, uses separators 21, 22 as separators in the light of a conventional one, and is provided with a water permeable film 23 having moisture permeability. The separator 21 has a humidifying part for fuel gas on the side surface 81b side to the conventional example. Namely, the separator 21 has a recessed groove 211A and a peripheral part 214 for installing the water permeable film 23 on the side surface 81b side. The fuel gas passing in the groove 211A is humidified through the water permeable film 23 by a heat medium (water) passing in a groove 821B which is a heat exchange part possessed by an adjacent unit cell 2. |
