Abstract
A structure of a cathode electrode for a fuel cell includes a catalyst layer formed by mixing a carbon material with a catalyst material and a hydrophilic ion conductive material. The hydrophilic ion conductive material is embedded on the catalyst layer and contacts an electrolyte membrane and a diffusion layer to provide a migration path for water and hydrogen ions.
