  • Patent number: 12155101
    Abstract: A method for producing a membrane electrode assembly for a fuel cell comprising a proton exchange polymer membrane, catalyst layers, and first and second gas diffusion layers, the method comprising the following steps: a) forming a catalytic layer coating on a first surface of the membrane, the opposite surface being supported by a spacer; b) forming a catalytic layer coating on a first surface of the first gas diffusion layer; c) bringing the first surface of the first gas diffusion layer into contact with the surface opposite to the said first surface of the membrane, after removing the spacer, and bringing the first surface of the membrane into contact with a surface of the second gas diffusion layer.
    Type: Grant

  • Patent number: 10826080
    Abstract: A fuel cell including: a membrane/electrode assembly including a proton exchange membrane and including an anode in contact with the membrane, the membrane/electrode assembly including a first active zone covered by the anode, and a first linking zone not covered by the anode; flow guiding plates between which the membrane/electrode assembly is arranged, the flow guiding plates being traversed by at least one first flow collector in communication with the anode, the first linking zone arranged between the first flow collector and the first active zone. The membrane/electrode assembly further includes a first capacitive layer including a mixture of carbon including a BET specific surface area at least equal to 200 m2/g and of a proton-conducting material, arranged on the first linking zone.

  • Publication number: 20190280321
    Abstract: The invention relates to a fuel cell comprising a membrane/electrode assembly (14), that includes: a proton exchange membrane (2); an anode (31) which is in contact with a first surface of the membrane and which contains a mixture including a proton conducting polymer and platinum supported on carbon powder; said mixture further includes additional carbon which does not support any catalyst and which has a minimum specific surface area BET of 200 m2/g. The membrane/electrode assembly (14) has a first active region (21) that is covered by the anode (31), and a first joining region (22) that is not covered by the anode (31).
