MANUFACTURING METHOD FOR FUEL CELL

A manufacturing method for a fuel cell may comprise preparing an electrode sheet including at least an electrolyte membrane; arranging a joining material constituted of a thermoplastic resin in a frame shape on the electrolyte membrane; arranging a support frame having an opening on the joining material arranged on the electrolyte membrane; performing a first laser irradiation process in which the support frame is irradiated with a laser beam such that a first portion of the joining material between the support frame and the electrolyte membrane melts and the electrolyte membrane and the support frame are welded to each other; and performing a second laser irradiation process in which a second portion of the joining material that is positioned inside the opening of the support frame is irradiated with a laser beam such that the second portion of the joining material melts and is welded to the electrolyte membrane.
