ELECTRODE CATALYST FOR FUEL CELL, METHOD OF PREPARING THE SAME, MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL INCLUDING THE SAME

摘要

An electrode catalyst for a fuel cell, a method of preparing the same, and a membrane electrode assembly and a fuel cell including the same. The electrode catalyst includes a catalyst particle that incorporates a plurality of palladium atoms, a plurality of atoms of a transition metal, and a plurality of atoms of a precious metal having a higher standard reduction potential than the transition metal, where all of the plurality of atoms of the transition metal are respectively surrounded by at least one of the palladium atoms, the neighboring atoms of the transition metal, or the atoms of the precious metal.
