1. A closed loop reactant/product management system for electro-chemical galvanic energy devices, the system comprising:
- a. fuel cell means comprising first and second internal reactant gas conduit means, and internal coolant liquid conduit means;
b. first and second reactant gas supply connecting means;
first inlet line means for pressure-tight gas flow connection from said first reactant gas supply connecting means to said first internal reactant gas conduit means;
second inlet line means for pressure-tight gas flow connection from said second reactant gas supply connecting means to said second internal reactant gas conduit means;
c. indirect heat exchanger means in fluid flow connection with the internal liquid flow conduit means;
d. first liquid-gas separator and liquid reservoir means in pressure-tight fluid flow connection with the heat exchanger means and with the internal liquid flow conduit means and with the first internal gas flow conduit means;
e. second liquid-gas separator and liquid reservoir means in pressure-tight fluid flow connection with said second internal gas flow conduit means;
f. first gas repressurization means between said first liquid-gas separator means and said first internal reactant gas conduit means to increase the pressure of the first gas applied to said first internal gas flow conduit means; and
g. second gas repressurization means between said second liquid-gas separation means and said second internal reactant gas conduit means to increase the pressure of the second gas applied to said second internal gas flow conduit means.

Abstract
The present invention teaches a closed loop energy system including means capable of managing both cooling cycle and the fuel/oxidant gas flow in conjunction with a fuel cell. The system includes a plurality of galvanic cells, gas flow conduit means, internal fluid flow conduit means, heat exchanger means, liquid-gas separator means, and gas repressurization means.
