A manufacturing process includes: depositing a first catalyst on a first gas diffusion layer (GDL) to form a first catalyst-coated GDL; depositing a first ionomer on the first catalyst-coated GDL to form a first gas diffusion electrode (GDE); depositing a second catalyst on a second GDL to form a second catalyst-coated GDL; depositing a second ionomer on the second catalyst-coated GDL to form a second GDE; and laminating the first GDE with the second GDE and with an electrolyte membrane disposed between the first GDE and the second GDE to form a membrane electrode assembly (MEA). A MEA includes a first GDL; a second GDL; an electrolyte membrane disposed between the first GDL and the second GDL; a first catalyst layer disposed between the first GDL and the electrolyte membrane; and a second catalyst layer disposed between the second GDL and the electrolyte membrane, wherein a thickness of the electrolyte membrane is about 15 &#x3bc;m or less.
