FIELD: transport.
SUBSTANCE: invention relates to spacecraft hardware, particularly to electric power plants. Proposed electrolysis unit comprises solid-polymer electrolytic cell connected to spacecraft power supply system and water supply system. The latter incorporates circulation pump, water circulation oxygen and hydrogen circuits. Each said circuit comprises appropriate chamber of electrolytic cell and gas separator composed by rotary separator. Separators are connected with DC electric drive of circulation pump. This electric drive is connected with spacecraft power supply system in series with electrolytic cell. Oxygen circuit is equipped with input water line with valve and accommodates heat exchanger connected to spacecraft thermal control system.
EFFECT: stable operation, higher reliability.
