METHOD OF MIXING FINE-GRAINED PARTICLES OF CARBON-BASED ELECTROCATALYSTS IN VACUUM Russian patent published in 2014 - IPC B22F1/02 C23C14/34 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of electrochemistry, namely to a method of mixing particles of carbon-based electrocatalysts in vacuum, which consists in the fact, that mixing is carried out in a vacuum work chamber, equipped with a device for an inert gas supply and a holder of powder of particles of the electrocatalysts. Mixing is realised by the creation of a fluidised layer. The method is characterised by the fact, that for placement of the electrocatalyst powder applied is a porous substrate with open porosity, made from an inert material, pneumatically connected to a device of autonomous gas supply, placed in the holder, and the inert gas is blown through the porous substrate with the formation above the substrate of the fluidised layer of the electrocatalyst particles.

EFFECT: application of the claimed invention makes it possible to increase efficiency of its application for the electrochemical catalysts on carbon carriers, such as soot, nanotubes or nanofibres, possessing a highly developed surface, by the reduction of the particles adhesion and ensuring their rotation in the fluidised layer.
