This chapter describes a spray-based method to manufacture electrocatalyst powders for fuel cell and related applications. The attributes of this process are compared to traditional solution precipitation/impregnation methods as well as non-powder-based electrocatalyst production methods. The spray-based process described here results in formation of unique spherical, micrometer-sized aggregates consisting of sub-micrometer electrocatalyst particles where the nanometer sized active phases (Pt, PtRu, metal alloys, metal oxides, composite and anchored molecular compounds) are highly dispersed on the surface of carbon supports. The advantages of this method to manufacture electrocatalyst powders are described in terms of process economics and performance.
