ELECTRODE OF PARTICLES INCLUDING BORON VALVE METAL, OR IRON GROUP AND ACTIVE PARTICLES

摘要

An electrode of the type of a composite product has a layer of matrix particles, applied to a base by a thermal spraying process. Electrochemically active particles having a particle size smaller by at least one order of magnitude are surface bonded to the matrix particles prior to the spraying onto the base. The disclosed electrocatalyst is metal of the platinum or iron groups. The matrix particles are conductive but have a lesser electrochemical activity than that of the active particles. The matrix material is selected from the group consisting of oxides and carbides of titanium.
