The electrochemical direct current generator for space system Buran

Abstract The electrochemical generator FOTON is designed for the “Energia-Buran” space system. Its operating power ranges from 0 to 16 kW. Allowable short-time overload is 25 kW. At nominal load (10kW) the efficiency is 65%. The stack design of the generator allows an output voltage of several hundred volts with unchanged power. The new electrode assembly is 0.9 mm thick; 1 cm 2 of it weighs 0.28 g.
