Abstract:
A unique, current conducting, separator element with controlled anolyte flow distribution is incorporated in an electrolysis cell having anode and cathode electrodes bonded to an ion transporting membrane. The current conducting-fluid distributing separator has a plurality of parallel conductive ribs which contact the anode electrode and also define a plurality of fluid distribution channels through which an anolyte such as water, is brought to the electrode and through which gaseous electrolysis products and the spent anolyte are removed from the anolyte chamber. A pressure dropping flow restrictor is provided in the channel inlets to prevent gases generated at the anode from flowing backward and blocking the anolyte distribution inlet manifold. The pressure dropping element can take the form of a restrictor to reduce the dimension of the channel. Alternatively the separator is molded so that the inlets of the channels have a reduced cross section.
