1. A closed loop reactant/product management system for electrochemical galvanic energy devices, the system comprising:

  • (a) a modular package comprising a plurality of galvanic cells, two internal gas flow conduit means for independently carrying each of two gaseous reactants, which form a liquid product within the galvanic cells, and an internal liquid flow conduit means for independently carrying a cooling liquid to the galvanic cells, the cooling liquid being derived from the liquid product;

    (b) first and second gas supply connecting means each designed to provide make-up gaseous reactants, respectively, to the system;

    (c) indirect heat exchanger means in fluid flow connection with the internal liquid flow conduit means;

    (d) first and second liquid-gas separator means and first and second liquid reservoir means, the respective separator means and reservoir means being in open fluid flow connection, each of the reservoir means being designed to provide a liquid-free, gas-filled space in an upper portion thereof and to maintain liquid in the lower portion, the first reservoir means being in pressure-tight fluid flow connection with the heat exchanger means and with the respective internal liquid flow passage, each of the first and second reservoir means being in pressure-tight fluid flow connection with the respective first and second gas supply connecting means, and the first and second liquid-gas separator means being in pressure tight fluid flow connection with the respective gas flow conduit means; and

    (f) gas repressurization means between each of the gas flow conduit means and the respective liquid-gas separator means, designed to increase the pressure of gas from the internal gas flow conduit means.
