Modified carbon or graphite fibrous percolating porous electrode, its use in electrochemical reactions

摘要

This invention concerns a fibrous percolating porous electrode of the type containing a fibrous porous matrix made of carbon or graphite. PPThe 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.
