Abstract: An electrode assembly for an electrolysis cell is provided comprising at least two opposed electrode working faces, and placing between the working faces a resilient, compressible member against which compression of the electrode takes place during its insertion into the cell. Upon inserting said electrode assembly into a smaller opening within the cell, which opening is defined by the adjacent electrodes, compression of the resilient, compressible elastic member through insertion of the electrode assembly into the opening takes place and automatically guides the assembly such that its working faces are correctly positioned relative to the adjacent electrodes. The degree of compression of each electrode assembly is determined by spacer assembly guides or appendages mounted on the electrode face. These guides determine the gap between the electrode face and adjacent electrodes.
