Abstract: A water electrolysis system includes a water electrolysis cell stack having an anode and a cathode. A water storage tank having an outlet is disposed above the cell stack and communicates with an inlet of one of the anode and the cathode of the cell stack for gravity feeding water from the water storage tank to the cell stack. A phase separator is disposed below and in communication with the water storage tank. The phase separator has an inlet for receiving a two phase stream including water and product gas exiting an outlet of the one of the anode and cathode of the cell stack, and includes a conduit having a lower end disposed within the phase separator for receiving water recovered in the phase separator. The conduit has an upper end extending into the water storage tank. Further, the conduit defines a plurality of openings along a portion of the conduit disposed in the phase separator such that the product gas received in the inlet of the phase separator enters the inside of the conduit through the openings and entrains and lifts water upwardly therewith through the conduit and into the water storage tank whereby water is recirculated through the cell stack.

Abstract: An electrochemical cell electrode plate structure, a high-pressure electrochemical cell device, and a method for preparing such devices, are provided. The inventive electrode plate structure comprises a laminar assembly of slotted plate-shaped components that provides more uniform openings or flow passages across the active areas thereof. The inventive high-pressure electrochemical cell device comprises at least one cell made up of both slotted and unslotted plate-shaped components that are free of material deformations typically resulting from the high compressive force employed during final cell assembly. The inventive method for preparing such devices basically involves preparing at least one laminated sub-assembly comprising unslotted component layers for the purpose of consolidating such weaker layers into stronger sub-assemblies prior to a final lamination step.

Abstract: An electrically non-conductive plate structure, for use in high pressure electrochemical cells employing ion-exchange membranes that creep or flow under pressure, is provided. Such plate structures are provided with a means for impeding membrane creep or flow when the cells are subjected to high axial loadings. When two such structures are positioned on either side of an ion-exchange membrane, so as to forcibly contact the surfaces thereof, such structures serve to contain, and thereby form a fluid tight seal with, the membrane while maintaining the electrical integrity of the cell.
