ABSTRACT:
Due to the limited structural integrity of the ion exchange membrane, operation at pressure gradients exceeding about 200 psi can cause electrolyzer failure due to the ion exchange membrane being physically forced into the holes of the screen set forming the chamber on the lower pressure side of the ion exchange membrane. Utilizing a porous sheet between the anode electrode and the screen set provides additional structural integrity to the ion exchange membrane and allows simultaneous dual-directional flow of water to the anode electrode while oxygen flows from the anode electrode, thereby allowing high pressure gradient operation.
