Zusammenfassung:	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 relatively low temperature, such as not greater than about 400 DEG C. L'invention concerne des poudres électrocatalytiques et des procédés de préparation des ces poudres, telles que des poudres électrocatalytiques composites de carbone. Les poudres présentent une microstructure et une morphologie bien contrôlées. Le procédé consiste à former les particules à partir d'un aérosol de précurseurs par chauffage de l'aérosol à une température relativement basse, c'est-à-dire égale ou inférieure à environ 400 DEG C.
