Abstract
A porous plate for an electrochemical cell, such as plates 22, 24 having a sealing material disposed in an edge region 41 of the plate is disclosed. Various construction details including a method for making the plate are disclosed which increase the cross pressure material the plate can withstand. In one embodiment, the seal region 41 is impregnated with powder having a low structure and predetermined particle size using a pressurized liquid carrier.
