Adhesion structure of single cell of fuel cell stack and adhesive sheet for single cell of fuel cell stack

摘要

Problem to be solved: to provide an adhesion structure for a single cell of a fuel cell stack capable of easily adhering a membrane electrode assembly, a frame member, and a separator, and an adhesion sheet for a single cell of a fuel cell stack.The adhesive structure of a single cell of the fuel cell stack is made of a hard resin frame 10 having an opening 11 in the center, a mea 20 overlaid on one surface of the frame member 10 and covering the opening 11 Then, the present invention is applied to a single cell of a fuel cell stack having a separator 30 superposed on one of the surfaces of the frame member 10, and the MEA 20 and the separator 30 are bonded to the frame member 10.An adhesive sheet 40 having a first adhesive portion 40A extending along the periphery of the opening 11 and bonding the frame member 10 and mea 20 together, and a second adhesive portion 40B which is connected to the outer peripheral side of the first adhesive portion 40A and adhered to the frame member 10 and the separator 30 is provided.Diagram
