ELECTROCATALYST POWDERS, METHODS FOR PRODUCING POWDERS AND DEVICES FABRICATED FROM SAME

摘要

Electrocatalyst powders and methods for producing electrocatalyst powders, such as carbon composite electrocatalyst powders. The powders have a well- controlled microstructure and morphology. The method includes forming the particles from an aerosol of precursors by heating the aerosol to a relative ly low temperature, such as not greater than about 400~C.
