Oct 19, 2017 · A typical proton exchange membrane fuel cell (PEMFC) catalyst layer is a porous, three dimensional structure consisting of carbon support, platinum (Pt) or Pt-alloy catalyst and ionomer such as Nafion ®, all in intimate contact. The carbon support enhances the bulk electronic conductivity of the electrode and dispersion of the catalyst nanoparticles.
