(EP947020-A1)      An electrochemical cell electrode plate consists of a laminar assembly of 1st and 2nd plates. Each plate has a central portion with openings or fluid flow spaces, and a solid frame integral with the central portion and with at least one aperture and slots forming discontinuous partial channel(s) between the aperture(s) and central portion. The apertures form continuous fluid flow conduits through the assembly. The openings are offset from each other to form reduced area fluid flow spaces. The discontinuous partial channels communicate to from a continuous passage to allow fluid communication between the apertures and reduced area openings. Also claimed are: (i) a high pressure electrochemical cell device consisting of the above laminar assembly and an electrolyte; and (ii) the assembly of the components to form the above cell device.    Preferably, when the plates are bonded to form the cell device, the bonding material is a fluoroelastomer, silicone or epoxy. Preferably, a 5:1 solution of fluoroelastomer in an aliphatic ketone solvent.    USE -   For electrolysis of water or other liquids, or to catalytically combine H2 or other gaseous fuel and O2 in a fuel cell to generate electricity.    ADVANTAGE -   The device can operate at extremely high pressure for long periods of time, has more uniform openings across the active areas of the electrode plates, has improved adhesion between cell components, heightened strength requirements and free from material deformations.
