APPARATUS FOR ELECTRICALLY CONNECTING CELL MODULES OF A METAL OXIDE-HYDROGEN BATTERY

An apparatus for electrically connecting cell modules of a metal oxide-hydrogen battery. The battery includes an outer pressure vessel containing a plurality of cell modules which are each sealed in a plastic bag and each cell module is provided with a vent which is permeable to the flow of gas but impermeable to the flow of liquid electrolyte. A pair of annular electrical conductors are associated with each cell module and extend through aligned holes in the bag. The conductors of each cell module are electrically insulated from each other and are disposed around an insulating tie rod. One of the conductors is connected to the positive terminals of the cell module, while the other of the conductors is connected to the negative terminals. A series of spring washers are mounted on the tie rod and urge the portions of each bag bordering the holes therein into tight sealing relation with the flange of the respective conductor to prevent leakage of the electrolyte through the holes in the bag.
