UNDERWATER APPARATUS POWER INSTALLATION Russian patent published in 2008 - IPC H01M16/00 H01M8/06 

FIELD: power installations incorporating electrochemical generator.

SUBSTANCE: proposed power installation has electrochemical generator incorporating oxygen supply line communicating with oxygen storage and treatment unit, water drain line communicating with water accumulation tank, hydrogen supply line communicating with hydrogen outlet line of water-activated chemical current supply with gas cushion incorporating soluble metal anode and inert catalytic cathode both installed in sealed tank filled with aqueous solution of electrolyte which is provided with electrolyte level sensor and communicates with water supply line and with solid-phase reaction product accumulation line, voltage converter whose inputs are connected to electric outputs of electrochemical generator and chemical current supply, outputs being connected to users. Newly introduced in power installation are at least two groups of reversible hydrogen storages with hydrogen filling and draining lines for alternate connection through controlled valves to line for hydrogen outlet from sealed-bowl gas cushion of water-activated chemical current supply and with hydrogen supply lines of electrochemical generator. Hydrogen storages are provided with heat-transfer surfaces connected via lines to coolant heating and cooling systems and accommodating valves affording alternate heat supply to one of hydrogen storage groups and heat transfer from other group; hydrogen storage filling line communicates with water admixture accumulating system through periodically opened valve. Hydrogen filling capacity of each group of hydrogen storages is not over 20% of that required to ensure desired rated capacity of power installation.

EFFECT: enhanced safety and functional efficiency of electrochemical generator.
