Abstract Porous Plate for an Electrochemical Cell and Method for Making the Porous Plate A seal structure for a porous plate of an electrochemical cell includes a sealing material disposed in a seal region of the plate to form a hydrophilic barrier to gas with an electrolyte and a hydrophobic layer to block the loss of electrolyte from the hydrophilic layer is disclosed. Various construction details including a method for making the plate are disclosed which increase the cross pressure the sealing region of the plate can with- stand. In one embodiment, the seal region is impregnated with powder having a low structure and predetermined particle size using a pressurized liquid carrier. A FEP Teflon ? film bonds adjacent electrolyte reservoir plates together.
