A MEMBRANE-ELECTRODE BINDER HAVING A DUAL ELECTRODE, THE MANUFACTURING METHOD THEREOF, AND A FUEL ELECTRODE COMPRISING THEREOF |
摘要 |
A membrane-electrode binder for a fuel cell, a method for preparing the membrane-electrode binder, and a fuel cell containing the membrane-electrode binder are provided to increase the adhesive strength with the polymer electrolyte membrane and to inhibit the discharge of the inorganic acid of the polymer electrolyte membrane. A membrane-electrode binder comprises a dual electrode which comprises a first electrode(11) and a second electrode(12); and a polymer electrolyte membrane(10) which is located on the dual electrode and is in contact with the first electrode, wherein the first electrode is prepared by using a PBI(polybenzimidazole)-based binder to increase the adhesive strength with the polymer electrolyte membrane, the second electrode is prepared by using a PTFE-based binder to inhibit the discharge of the inorganic acid of the polymer electrolyte membrane, and the polymer electrolyte membrane is a PBI-based polymer electrolyte membrane doped with an inorganic acid. |
