The present invention is directed to sol-gel derived electrode structures and sol-gel derived electrode assemblies associated with fuel cell systems, as well as to methods relating thereto. In one embodiment, the present invention is directed to electrode structure adapted for use with a fuel cell system such as, for example, a direct methanol fuel cell system. In this embodiment, the invention may be characterized in that the electrode structure comprises a support substrate or structure having a one or more discrete porous regions, wherein each of the one or more discrete porous regions comprise a sol-gel. The sol-gel of the present invention comprises platinum ruthenium dioxide, platinum-ruthenium-silicon oxide, platinum-ruthenium-titanium oxide, platinum-ruthenium-zirconium oxide, platinum-ruthenium-aluminum oxide, or a combination thereof, preferably, however, the sol-gel comprises platinum ruthenium dioxide. |
