摘要： A method of forming a fuel cell catalyst layer. The method includes spinning a composition including a base polymer, a solvent, and a catalyst precursor into a non-woven fiber mat having the catalyst precursor embedded therein. The method further includes carbonizing the non-woven fiber mat to form a carbon fiber substrate. The method also includes reacting the catalyst precursor to form a plurality of individual catalyst particles embedded in the carbon fiber substrate.

摘要： In one or more embodiments, an electrochemical device includes a substrate having a substrate surface; an amorphous metal oxide layer supported on the substrate surface; and a noble metal catalyst supported on the amorphous metal oxide layer to form a catalyst layer. The amorphous metal oxide layer may contact only 25 to 75 percent of the substrate surface. The amorphous metal oxide layer may include less than 10 weight percent of crystalline metal oxide. In certain instances, the amorphous metal oxide layer is substantially free of crystalline metal oxide.
