RUTHENIUM CATALYST FOR PROX REACTION OF CARBON MONOXIDE, METHOD OF MANUFACTURING THE RUTHENIUM CATALYST, AND FUEL CELL SYSTEM INCLUDING THE RUTHENIUM CATALYST

摘要

Disclosed is a ruthenium catalyst that promotes a preferential oxidation (PROX) reaction. The ruthenium catalyst is a carrier; and a ruthenium active ingredient supported on the surface of the carrier, wherein the ruthenium active ingredient is supported on the surface of the carrier in an amount of 0.07 to 0.25 μmol/m 2 .
