Abstract

After passing through a gap (15) defined between a suction roller (20) and a separation roller (11), an electrolyte membrane (92) is held on the suction roller (20) under suction, and a base material (91) is transported away from the outer peripheral surface of the suction roller (20). Thus, the base material (91) is separated from the electrolyte membrane (92). At this time, a gas is blown toward a plurality of ejection regions lying on the outside surface of the electrolyte membrane (92). The ejection regions are discontinuous in the width direction of the electrolyte membrane (92) and include opposite edges of the electrolyte membrane (92) as seen in the width direction. This suppresses the lift of the electrolyte membrane (92) on the opposite edges of the electrolyte membrane (92) as seen in the width direction where the force of suction is poor. The ejected gas passes through spaces defined between the ejection regions. This reduces the amount of gas flowing toward a catalyst supply part.
