The present invention relates to SiC nanostructures, including SiC nanopowder, SiC nanowires, and composites of SiC nanopowder and nanowires, which can be used as catalyst supports in membrane electrode assemblies and in fuel cells. The present invention also relates to composite catalyst supports comprising nanopowder and one or more inorganic nanowires for a membrane electrode assembly. L'invention concerne des nanostructures SiC, comprenant une nanopoudre SiC, des nanofils SiC et des composites de nanopoudre et de nanofils SiC, qui peuvent être utilisés comme supports de catalyseur dans des ensembles électrodes à membrane et dans des piles à combustible. L'invention concerne également des supports de catalyseur composites comprenant une nanopoudre et un ou plusieurs nanofils inorganiques destinés à un ensemble électrode à membrane.
