Abstract
The method comprises forming a dry preunit including a stack of cells. Each cell is formed by placing sequentially a conductive support sheet coated on one or both sides with a porous conductive material except at the perimeter edge surfaces, an ion permeable or semi-permeable space separator, a gasket, at least one hollow capillary tube having a melting point higher than the gasket material. Upon heating the gasket material flows, adheres to, and seals the edges of the stack creating a solid integral stack of layers of alternating electrically conductive sheet coated with a porous electrically conducting material and a separator. The gasket material creates a continuous integral external polymer enclosure having hollow capillary tubes. After an electrolyte is introduced into the preunit, the capillary tubes are sealed.
