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.
摘要翻译：公开了一种膜 - 电极组件（MEA），其防止在单个电池或一堆燃料电池的制造时电解质膜被损坏。 MEA还包括插入传统垫圈之间的防护垫片，其中防护垫片具有对应于电解质膜厚度的70％-95％的厚度。 MEA确保电解质膜的机械保护，从而防止电解质膜在单个电池或一堆燃料电池的制造时被过大的结合压力损坏。此外，可以使电解质膜与催化剂层之间的接触电阻和气体扩散层与催化剂层之间的接触电阻最小化，从而提高燃料电池的质量。

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 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 method for in-situ preparation of a polybenzimidazole-based electrolyte membrane, including: polymerizing a polybenzimidazole polymer in a solution; casting a solution containing the polymerized polymer onto a substrate and drying the solution in air to form a membrane; washing the dried membrane with water or alcohol; and allowing water or alcohol to evaporate from the membrane containing water or alcohol, while maintaining the shape of the membrane. The method for in-situ preparation of a polybenzimidazole-based electrolyte membrane allows easy preparation of a polybenzimidazole-based electrolyte membrane having a desired area without any complicated processes, and thus contributes to simplification of an overall process for fabricating a fuel cell.
