摘要：
The cathode catalyst includes a zeolite-containing carrier, and a ruthenium (Ru)-M-tellurium (Te) alloy supported on the carrier, where M is selected from the group consisting of tungsten (W), molybdenum (Mo), and combinations thereof. The cathode catalyst has a high activity and selectivity for a reduction reaction of an oxidant, and is highly stable under an acidic atmosphere thereby being capable of improving performances of a membrane-electrode assembly and fuel cell system.
