Tungsten-containing fuel cell catalyst and method of making same

This invention is related to catalysts for fuel cells. More, particularly, this invention is related to tungsten-containing compounds which are useable as fuel cell catalysts. A tungsten-containing fuel cell catalyst having high electrochemical activity and its method of making are described. The tungsten-containing catalyst may be formed in situ in a fuel cell after the fuel cell is assembled. The catalyst is formed by a low temperature electrochemical activation of a tungsten-containing precursor which has been deposited on a carbon support
