  "textContent": "A method of making a catalyst layer of a membrane electrode assembly (MEA) for a polymer electrolyte membrane fuel cell includes the step of preparing a porous buckypaper layer comprising at least one selected from the group consisting of carbon nanofibers and carbon nanotubes. Platinum group metal nanoparticles are deposited in a liquid solution on an outer surface of the buckypaper to create a platinum group metal nanoparticle buckypaper. A proton conducting electrolyte is deposited on the platinum group metal nanoparticles by electrophoretic deposition to create a proton-conducting layer on the an outer surface of the platinum nanoparticles. An additional proton-conducting layer is deposited by contacting the platinum group metal nanoparticle buckypaper with a liquid proton-conducting composition in a solvent. The platinum group metal nanoparticle buckypaper is dried to remove the solvent. A membrane electrode assembly for a polymer electrolyte membrane fuel cell is also disclosed.",
