Fuel cell electrode and method of making and using same
Patent
·
OSTI ID:6103272
A method is described for making a fuel cell electrode comprising applying a layer comprising a hydrophobic polymer and an electro-catalyst to one surface of a porous substrate, heating the substrate and the layer to a temperature at or above the melting temperature of the polymer and below the decomposition temperature of the polymer while simultaneously compressing the substrate and the layer at a pressure between bout 20 psia and about 100 psia. The heating and compressing is continued for a time period of between about 10 minutes and about 20 minutes, the fuel cell electrode providing increased peak performance as well as improved performance stability.
