CATALYSTS FOR ANODE OF DIRECT METHANOL FUEL CELL, PREPARATION METHOD THEREOF, MEMBRANE ELECTRODE ASSEMBLY FOR DIRECT METHANOL FUEL CELL AND DIRECT METHANOL FUEL CELL SYSTEM USING THE SAME

摘要

PURPOSE: A catalyst for an anode electrode is provided to implement the excellent performance and long term durability in the high methanol concentration and relieve a crossover of the direct methanol fuel cell. CONSTITUTION: A catalyst for an anode electrode of a direct methanol fuel cell includes silica; and the catalytic substance which is dipped in the silica; the catalytic substance comprises one or two kinds which is selected from platinum, ruthenium, osmium, platinum-ruthenium alloy, platinum-osmium alloy, platinum-palladium alloy, platinum-M alloy; the M is a transition metal of more than one kind which is selected from Ga, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sn, Mo, W, Rh, and Ru. The catalyst comprises 50-80 parts by weight of the catalytic substance base on 10-40 parts by weight of the silica.
