Abstract
Cell having a porous, self-draining, gas diffusion electrode contained within a frame and having on both sides of said electrode a liquid permeable microporous diaphragm. The electrode assembly contains an internally positioned current distributor. The cell has two oppositely charged electrodes separated by the electrode assembly which divides a single electrolyte compartment. In operation, electrolyte is flowed into the electrolyte compartment and spent electrolyte is removed. In one embodiment of the invention, the electrolyte is internally circulated by turbulent flow of electrolyte as the result of the upward movement of gas released at an electrode.
