Abstract

In the electrode in the form of a rectangular parallelepiped composed of impregnated graphite material for electrochemical reactors, the electrode (4,5) is provided with openings (8,9,10,11) extending perpendicular to its active electrode surfaces (6,7) at its corners. Canals (12,13) which extend parallel to the active electrode surfaces (6,7) in the direction of an adjacent opening (9,10) originates in each case from two openings (8,10) situated diagonally opposite each other. The canals (12,13) have communicating channels (14,15) to the active electrode surfaces (6,7).
