PROBLEM TO BE SOLVED: To provide a manufacturing technique capable of suppressing increase in the ventilation resistance of a porous film, when manufacturing a reinforced electrolyte film reinforced with the porous film.SOLUTION: A lamination section 100 includes an air nozzle 120 oppositely to a lamination roll 110 to which a first electrolyte membrane base material sheet Ms1, where a sheet-like electrolyte membrane Ms is formed on a back sheet Bs, and a porous film sheet Ps are fed. On the surface of a blowout region of air from the air nozzle 120, the lamination roll 110 laminates the first electrolyte membrane base material sheet Ms1 and porous film sheet Ps by superposition. In the midst of such lamination, the lamination section 100 blows pressurized air from the air nozzle 120 toward the porous film sheet Ps. The porous film sheet Ps receives blowout of the pressurized air and is stuck to the electrolyte membrane Ms of the first electrolyte membrane base material sheet Ms1.SELECTED DRAWING: Figure 3 |
