Integrated membrane and electrode support screen and protector ring for an electrochemical cell

摘要

The present invention is an integrated screen comprising a screen portion having openings and an integral protector edge disposed about the periphery of the screen portion. This integrated screen protector edge can be utilized individually as the membrane support/flow field in an electrochemical cell or in conjunction with one or more subsequent screen layers. When utilized with subsequent screen layers, the integrated screen protector edge is disposed adjacent to and in intimate contact with the membrane assembly.
