Abstract

A carbon monoxide (CO) tolerant membrane electrode assembly (MEA) includes an ionically-conductive proton exchange membrane, an anode contacting a first side of the membrane and including a hydrophobic bonding agent, an ionomer bonding agent, first catalyst particles, second catalyst particles, and an anode gas diffusion layer (GDL), a cathode contacting a second side of the membrane and including a cathode GDL. The first catalyst particles are configured to preferentially catalyze oxidation of CO, and the second catalyst particles are configured to preferentially catalyze generation of hydrogen ions.
