Structuring in the formation technology of electrode material based on nafion proton-conducting polymer and thermally expanded graphite containing platinum nanoparticles on carbon black

Resumo

Laboratory production technique is described for fabrication of an electrode material containing platinum nanoparticles on carbon black, proton-conducting polymer Nafion, and thermally expanded graphite for direct-energy-conversion systems (fuel cells, electrolyzers, electrochemical sensors). Results of a study of the material by differential thermal analysis are presented. Scanning and transmission electron microscopy was used to examine the structure of the material, and its elemental composition was determined by the EDX method. Dependences of the porosity of the material on its composition are presented.
