  • Method and apparatus for manufacturing membrane electrode assembly
    Patent number: 11088378
    Abstract: A method and apparatus for manufacturing a membrane electrode assembly are provided, which can efficiently peel an electrode layer from a base material. A manufacturing apparatus for manufacturing a membrane electrode assembly of a fuel cell including a pair of electrode layers and an electrolyte membrane, the apparatus including: a transport device which transports the base material on which one cathode electrode layer of the pair of electrode layers is formed and which is connected to a transport sheet via an adhesive layer together with the transport sheet; a transfer device which transfers the one cathode electrode layer to the electrolyte membrane; a peeling device which peels the cathode electrode layer from the base material; and a cooling device having a spraying device which is directed to a start point portion for the peeling and sprays a cooling gas.
