燃料电池膜电极组合件和其制造方法
摘要：
一种具有燃料电极(4a)和氧化剂电极(4b)的燃料电池膜电极组合件，该膜电极组合件具有含非负载型催化剂的催化剂层(2)，催化剂层(2)包含未负载于载体上的0.3纳米至100纳米一次粒径的金属催化剂纳米颗粒(8)，该金属催化剂纳米颗粒(8)的电化学活性表面积是10m2/g至150m2/g，该含非负载型催化剂的催化剂层(2)的层厚度小于或等于10μm。
摘要（英）：

A fuel cell membrane-electrode assembly having a fuel electrode (4a) and an oxidant electrode (4b) has a non-supported-catalyst containing catalyst layer (2) that contains a metal catalyst nanoparticle (8) of 0.3 nm to 100 nm in primary particle diameter that is not supported on a support, and an electrochemically active surface area of the metal catalyst nanoparticle (8) is 10 m<2>/g to 150 m<2>/g, and a layer thickness of the non-supported-catalyst containing catalyst layer (2) is less than or equal to 10 mu m.
