A new method of fabricating fuel membrane electrodes was developed which yields polytetrafluoroethylenecontaining, platinum-black catalyzed electrodes which are highly active as hydrogen, hydrazine, methanol and propane anodes and as oxygen cathodes. The electrochemical activity of these membranes together with the activity of carbon-black polytetrafluorethylene membranes of similar structure has been measured in halfcell and full-cell experiments. The membranes containing carbon black appear to be promising as support structures for metal chelate catalysts. The electrode fabrication technique is simple and appears to be applicable to many other combinations of fuel cell catalyst or catalyst support powders and hydrophobic binder materials.
