Abstract

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.

Claims (6)

2. The cathode catalyst for a fuel cell set forth in claim 1, wherein said third component is one or more sorts of elements selected from tungsten and titanium.
3. The cathode catalyst for a fuel cell set forth in claim 2, wherein said third component is tungsten, comprising 0.5-10 of iron by weight and 5-50 of tungsten by weight when platinum is taken as 100 by weight.
4. The cathode catalyst for a fuel cell set forth in claim 2, wherein said third component is titanium, comprising 0.5-10 of iron by weight and 5-20 of titanium by weight when platinum is taken as 100 by weight.
5. The cathode catalyst for a fuel cell set forth in claim 1, wherein said support is a carbon powder.
6. The cathode catalyst for a fuel cell set forth in claim 1, wherein said fuel cell is a polymer electrolyte fuel cell.
