Abstract

A membrane electrode assembly (MEA) includes an ionically-conductive proton exchange membrane, an anode contacting a first side of the membrane and a cathode contacting a second side of the membrane and including third catalyst particles and a cathode GDL. The anode includes an anode gas diffusion layer (GDL), a first anode catalyst layer containing first catalyst particles, a hydrophobic polymer bonding agent, and a first ionomer bonding agent that lacks functional chains on a molecular backbone, and a second anode catalyst layer containing second catalyst particles and a second ionomer bonding agent that includes functional chains on a molecular backbone.
