PROCESS FOR MAKING MONO- OR BIPOLAR ELECTRODES FOR ELECTROCHEMICAL CELLS

摘要

The invention relates to a process for obtaining electrodes by depositing the active mass on the inert metallic support of mono or bipolar electrodes in electrochemical cells (cells, electrolysers). The process according to the invention consists in that a mixture containing 30 ... 30% water, 11 ... 15% detergent, 2,5 ... 3,5% spectral graphite are sprayed on a metallic blade support. ... 9% of active carbon, 30 ... 35% of powdered catalyst and 12 ... 16% of Teflon suspension, after which it is dried in infrared, is sterilized in air at 350 ... 400 ° C, and is hydrophilized with a 10% solution of polyvinyl alcohol.
