Abstract
An electrochemical battery made of stacked cells which are separated by separator plates comprising a good heat conductive material, e.g. nickel, stainless steel, copper. The separator plates extend beyond the edge of the stacked cells and outside the enclosure of the battery. The separator plates directly conduct heat, which is generated by the electrochemical process, from the battery cells to the ambient environment. Sealing of the enclosure between the separator plates is provided by an O-ring or, alternatively, by a bellows sealed to adjacent separator plates by O-rings. Sealing is possible for hydrogen at low pressure which is presented in batteries utilizing a metal-hydride hydrogen storage capacity.
