(US5316644-A)      An electrochemical cell electrode plate structure has two identical plate shaped components of high strength conductive material arranged facing each other. Each component has multiple flow passages that convert with other spaces in the assembly with a solid frame surrounding the central portion. Each frame has at least one discontinuous section which connects with another complementary assembly.    USE/ADVANTAGE -   Stacked electrolysis cells for use e.g. in the electrolytic prod. of oxygen and hydrogen or in fuel cell structures. Strong structures can be produced allowing usage at high pressures.    (JP7502306-W)      Electrochemical cell electrode plate comprises (a) laminar assembly of at least two identically configured plate-shaped components of an electrically conductive high-strength material having first major surfaces that are juxtaposed with one another in the assembly, and oppositely facing second major surfaces; (b) each of the components including a central portion having a multitude of fluid-flow spaces that communicate with the spaces of the respective other of the components in the assembly, and a solid frame integral with and circumferentially surrounding the central portion and provided with at least one through aperture therein that opens onto the first and second major surfaces and is aligned with an aperture of the other component in the assembly to form a continuous fluid-flow conduit therewith; and (c) the frame portion of each of the components having at least one channel therein that is situated between the aperture and the central portion and opens onto the first major surface, the channels of the two components communicating with one another in the assembly to complement each other into a continuous passage that establishes communication between the aperture and at least one of the spaces of the central portion of one of the components.    USE/ADVANTAGE -   In the high pressure electrochemical cell structure, the passage is partially formed in one of the components and partially in the other, the affected frame region of neither one of these components is weakened to the extent where its ability to withstand stresses would be compromised.
