  • Modified carbon or graphite fibrous percolating porous electrode, its use in electrochemical reactions
    Patent number: 4396474
    Abstract: 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.
    Type: Grant
    Filed: December 3, 1981
    Date of Patent: August 2, 1983
    Assignee: Societe Nationale Elf Aquitaine
    Inventors: Michel Astruc, Pierre-Yves Guyomar, Catherine Lestrade
