    摘要： A membrane-electrode binder for a fuel cell, a method of manufacturing the binder, and a fuel cell comprising the binder are provided, in which the membrane-electrode binder comprises a dual electrode constituted by a first electrode and a second electrode in a two-layer form, and a polymer electrolyte membrane disposed on the dual electrode, the dual electrode comprising an electrode substrate and a catalyst layer formed thereon. In detail, the membrane-electrode binder comprises the dual electrode that is constituted by the first electrode obtained by using a PBI-based binder, the second electrode obtained by using a PTFE-based binder, and an inorganic acid doped PBI-based polymer electrolyte membrane disposed on the dual electrode and coming in contact with the first electrode. In the configuration of the dual electrode, the PBI-based binder used for manufacturing the first electrode contributes to enhancing an adhesive strength with the inorganic acid doped PBI-based polymer electrolyte membrane, and the PTFE-based binder used for manufacturing the second electrode contributes to suppressing the emission of an inorganic acid from the inorganic acid doped PBI-based polymer electrolyte membrane, together improving the performance of a fuel cell.

    摘要： Disclosed is a membrane-electrode assembly (MEA) that prevents an electrolyte membrane from being damaged upon the fabrication of a single cell or a stack of fuel cells. The MEA further includes a guard gasket interposed between conventional gaskets, wherein the guard gasket has a thickness corresponding to 70%-95% of the thickness of the electrolyte membrane. The MEA ensures mechanical protection of the electrolyte membrane, and thus prevents the electrolyte membrane from being damaged by an excessive binding pressure upon the fabrication of a single cell or a stack of fuel cells. Furthermore, the contact resistance between the electrolyte membrane and the catalyst layer and the contact resistance between the gas diffusion layer and the catalyst layer can be minimized, thereby improving the quality of a fuel cell.
