  • Publication number: 20240136539
    Abstract: In an embodiment a method includes manufacturing a membrane-electrode-gas diffusion layer assembly (MEGA) fabric by bonding a gas diffusion layer (GDL) material to a first surface of a membrane-electrode assembly (MEA) fabric, injecting, by a steam injector, a liquid material to a first surface of the MEGA fabric while allowing the liquid material to be absorbed to the first surface of the MEGA fabric, supplying, by a gas injector, compressed gas to a second surface of the MEGA fabric in which the liquid material has been absorbed, inspecting, by a surface inspection device, a surface state of the MEGA fabric after supplying the compressed gas and, after inspecting, winding the MEGA fabric around a MEGA winding unit.

  • Publication number: 20230040167
    Abstract: Disclosed are a method of heat treating a membrane electrode assembly, in which a first membrane electrode assembly or the like is positioned between a first member and a second member and heat treatment is performed as at least one of the first member and the second member being a heating member, and also in which variation in the temperature of the membrane electrode assembly at different roll positions is decreased and interfacial bonding between the layers in the membrane electrode assembly is enhanced. Thus, the quality of the membrane electrode assembly, such as the durability and performance thereof, may be improved, the yield thereof may be increased, and the amount of heat treatment may be efficiently increased, thereby reducing costs through mass heat treatment and decreasing the rate of processing of the membrane electrode assembly.
