    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。
