摘要：
It is an object of the present invention to provide a cathode catalyst for fuel cells containing platinum and iron which can maintain the durability of a battery and can make a battery high output. The cathode catalyst for fuel cells comprises a supporting layer which consists of an alloy containing platinum and iron and further containing the third component which has an affinity for iron including one or more sorts of elements selected from the group consisting of tungsten, titanium, molybdenum, rhenium, zinc, manganese, tin, tantalum and rhodium, and a support on which the supporting layer is loaded. A catalyst using an alloy containing platinum and iron enables the batteries to become high output. By alloying one or more sorts of elements of the third component which has an affinity for iron with an alloy containing platinum and iron, it is possible to prevent eluting of the iron into the electrolyte.
摘要（中）：
本发明的目的是提供一种能够保持电池的耐久性并且能够使电池高输出的含有铂和铁的燃料电池用阴极催化剂。 用于燃料电池的阴极催化剂包括由含有铂和铁的合金组成的支撑层，并且还含有对铁的亲和性的第三组分，所述第三组分包括选自钨，钛，钼， 铼，锌，锰，锡，钽和铑以及负载载体的载体。 使用含有铂和铁的合金的催化剂使得电池变得高输出。 通过将具有与铁的亲和性的第三成分的一种或多种元素与含有铂和铁的合金合金化，可以防止铁向电解液中洗脱。
