Abstract
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.
