Abstract
Abstract The invention provides an electrode for use in an electrochemical reactor. The electrode comprising a plurality of metallic filaments consisting of carbon fibers coated with a metal, each of the metallic filaments being in electrical contact with at least several of the other metallic filaments for transmitting an electrical potential substantially throughout the electrode when the electrode is in use in the reactor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
An electrode for use in an electrochemical reactor the electrode comprising: a plurality of electrically conductive metallic filaments each of the filaments having a very small maximum thickness compared with the length of the filament and having a relatively good electrical conductivity, the filaments exhibiting little resistance to transverse deflection and being arranged in side by side relationship so that as electrolyte flows generally longitudinally over the filaments flow eddys will cause continuous transverse movements of the filaments relative to one another to enhance electrolytic action at the electrode and means retaining a portion of the filaments in electrical contact with one another over a discrete portion of the length of the filaments and providing electrical connection means for coupling the electrode to an external electrical circuit.
Claim 2
Dependent Claim
127 words

Claim 3
Dependent Claim
142 words
An electrode for use in an electrochemical reactor, the electrode comprising: a plurality of electrically conductive metallic filaments, each of the filaments having a very small maximum thickness compared with the length of the filament and having a relatively good electrical conductivity, the filaments exhibiting little resistance to transverse deflection and being arranged in side by side relationship, and means retaining the filaments in electrical contact with one another over at least two discrete portions of the lengths of the filaments, said portions being spaced apart from one another by a distance less than the length of the individual parts of the filaments extending between said discrete portions so that with the electrode in a horizontal position said individual parts sag and are free to move transversely relative to one another as electrolyte flows transversely between the filaments for enhanced electrolytic action.
