    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.
