RUTHENIUM-RHODIUM ALLOY ELECTRODE CATALYST AND FUEL CELL COMPRISING THE SAME

摘要

Disclosed is an electrode catalyst comprising a ruthenium (Ru)-rhodium (Rh) alloy. A membrane electrode assembly (MEA) comprising the same electrode catalyst and a fuel cell comprising the same membrane electrode assembly are also disclosed. The ruthenium-rhodium alloy catalyst has not only good oxygen reduction activity but also excellent methanol resistance compared to conventional platinum and platinum-based alloy catalysts, and thus can be used as high-quality and high-efficiency electrode catalyst having improved catalytic availability and stability.
