Abstract
Official abstract text for this publication.
The disclosure provides a manufacturing method for a fuel cell. The method includes a heating adhesion step in which a separator and a resin frame are adhered to each other. The heating adhesion step includes a plurality of heating steps in which a laminate is heated, and a conveyance step in which the laminate is conveyed between the heating steps. In the conveyance step, a support portion having a projecting portion projecting towards the laminate is used, and the laminate is supported only by the projecting portion and conveyed.
First claim
Opening claim text (preview).
What is claimed is: 1 . A manufacturing method for a fuel cell, comprising: a heating adhesion step in which a laminate is heated and a pair of separators and a resin frame are adhered to each other, the laminate having the separators, a membrane-electrode-gas diffusion layer assembly, and the resin frame surrounding the membrane-electrode-gas diffusion layer assembly, the membrane-electrode-gas diffusion layer assembly and the resin frame being disposed between the separators, wherein: the heating adhesion step has a plurality of heating steps in which the laminate is heated, and a conveyance step in which the laminate is conveyed between the plurality of heating steps; and in the conveyance step, a support portion having a projecting portion projecting towards the laminate is used, and the laminate is supported only by the projecting portion and conveyed. 2 . The manufacturing method according to claim 1 , wherein: the support portion is provided in a palette that conveys the laminate; and the support portion has an extending portion extending in a surface direction of the laminate. 3 . The manufacturing method according to claim 2 , wherein a sectional area of the extending portion is decreased gradually towards a distal end portion of the extending portion. 4 . The manufacturing method according to claim 1 , wherein the support portion supports a corner portion of the separator.
