    • 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.
    • 提供了一种用于燃料电池的膜 - 电极粘合剂,粘合剂的制造方法和包含该粘合剂的燃料电池,其中,所述膜 - 电极接合剂包括由第一电极和第二电极构成的双电极 并且设置在双电极上的聚合物电解质膜,所述双电极包括电极基板和形成在其上的催化剂层。 详细地说,膜 - 电极粘合剂包括由通过使用基于PBI的粘合剂获得的第一电极,通过使用PTFE基粘合剂获得的第二电极和无机酸掺杂的PBI基聚合物电解质构成的双电极 膜设置在双电极上并与第一电极接触。 在双电极的结构中,用于制造第一电极的PBI基粘合剂有助于提高与无机酸掺杂的PBI基聚合物电解质膜的粘合强度,并且用于制造第二电极的PTFE基粘合剂有助于 为了抑制无机酸掺杂的PBI系聚合物电解质膜的无机酸的排出,共同提高燃料电池的性能。
