PROBLEM TO BE SOLVED: To make narrow a region where an electrolyte membrane sheet may be creased or folded, in sheet joint work with exchange of former and new rollers.SOLUTION: In an MEA manufacturing device 100, a long electrolyte membrane sheet 20S is conveyed to an anode transfer mechanism part 110 and a cathode transfer mechanism part 120 together with a back sheet Bs, and an anode sheet 21S for forming an anode 21 and a cathode 22 are transferred. The electrolyte membrane sheet 20A is taken up by an electrolyte membrane sheet roll 20R together with the back sheet Bs while being formed in the back sheet Bs, and sent from the electrolyte membrane sheet roll 20R to a first transfer roller 112 and a second transfer roller 122 together with the back sheet Bs. The electrolyte membrane sheet roll 20R has already taken a dummy sheet DS which is continued to the back sheet Bs in which the electrolyte membrane sheet 20A has been already formed, around a take-up core 20Rc and sends out the dummy sheet Ds continuously after the back sheet Bs. |
