    Abstract: Disclosed is an electrode catalyst comprising: (a) a support with a specific surface area of at least 1200 m2/g; and (b) platinum or platinum-containing alloy particles on the support, wherein the platinum is supported on the electrode catalyst in an amount of 56˜90 wt % based on the total weight of the electrode catalyst. A membrane electrode assembly (MEA) comprising the electrode catalyst and a fuel cell using the MEA are also disclosed. The electrode catalyst comprises platinum or platinum-containing alloy particles highly dispersed on a support with a large surface area in an amount of 56 wt % or more, and thus has an extended catalytically active region, resulting in improvement in the quality of a fuel cell.

    Abstract translation: 公开了一种电极催化剂，其包含：（a）比表面积至少为1200m 2 / g的载体; 和（b）载体上的铂或含铂合金颗粒，其中基于电极催化剂的总重量将铂负载在电极催化剂上的量为56〜90重量％。 还公开了包括电极催化剂和使用MEA的燃料电池的膜电极组件（MEA）。 电极催化剂包含高度分散在具有56重量％以上的大表面积的载体上的含铂或含铂合金颗粒，因此具有延伸的催化活性区域，从而提高了燃料电池的质量 。
