Abstract:
An electrode for a fuel cell element including a hydrophobic graphite support layer; a semi-hydrophobic electro-catalyst layer including an electro-catalytically active material in a carbon substrate and a polytretrofluorethylene (PTFE) content having a first concentration; and a hydrophilic electro-catalyst layer including an electro-catalytically active material in a carbon substrate and having a PTFE content having a second concentration that is less than the first concentration.
