POWER PLANT OF SUBMERSIBLE CRAFT Russian patent published in 2002 - IPC

FIELD: power plants with electrochemical generators for submersible craft. SUBSTANCE: power plant has electrochemical generators using hydrogen-oxygen fuel cells, electrical equipment, cryogenic hydrogen and oxygen storage tanks with valves, hydrogen ventilation and afterburning device, water accumulation tank, and cooling circuit units all mounted in separate pressurized recesses; all pressurized recesses are disposed inside pressurized housing made in the form of modular compartment of submersible craft; each recess holding cryogenic hydrogen tanks with valves is, essentially, vertical pit disposed in modular compartment and welded into its housing with sealed manhole on upper lid; recesses for cryogenic oxygen tanks, electrochemical generators, air ventilation and hydrogen afterburning devices, reaction water dump tanks, and power plant electrical equipment are disposed at different elevations in modular compartment. EFFECT: enhanced power capacity, facilitated installation and maintenance, reduced harnessing, wiring, and repair charges, enhanced running characteristics and fire safety. 6 dwg
