Modified carbon or graphite fibrous percolating porous electrode, and electrochemical reactors fitted with such an electrode

摘要

This invention concerns a fibrous percolating porous electrode of the type containing a fibrous porous matrix made of carbon or graphite. The fibrous porous matrix, such as a carbon or graphite felt, is modified, for example by impregnation with a surface-active agent, and in the wetted state its apparent density in relation to water possesses specific values.
