Cathode catalyst for a fuel cell, a membrane-electrode assembly for a fuel cell, and a fuel cell system

摘要

The present invention relates to a cathode catalyst for a fuel cell, a membrane-electrode assembly for a fuel cell including the cathode catalyst, and a fuel cell system. The cathode catalyst includes a core including RuO₂, and Se and Pt. The Se and Pt are disposed to enclose the core. The cathode catalyst for a fuel cell of the present invention can have excellent catalyst efficiency, even if less platinum is included therein.
