A metal-gas electrochemical cell is disclosed wherein electrolyte is progressively supplied from a reservoir into the electrode or cell stack as needed, so as to maintain each stack component with adequate electrolyte, as the plates "grow" and absorb electrolyte with repeated cycling. The reservoir preferably is a compressible bladder positioned between one end of the plate stack and a retaining plate. As the plate stack "grows" with repeated cycling, the bladder is slowly compressed, forcing electrolyte from the bladder through an electrolyte distribution tube located within the plate stack. One end of the electrolyte distribution tube is fixed to an end plate of the plate stack and the second end of the distribution tube may be connected to a Belleville washer or other spring which acts through the distribution tube to compress the plate stack. The elasticity of the spring permits the stack to expand as the electrodes grow. |
