POWER STORING DEVICE
Document Type and Number:
Japanese Patent JP3105668
Kind Code:
B2
Abstract:
PURPOSE: To improve the operability in electrolysis and generation by setting the flowing direction of hydrogen or oxygen and steam supplied to steam electrolysis at electrolysis and generation in a fixed direction.
CONSTITUTION: In electrolytic operation, water is sent from a water tank 36 by a pump 37, mixed with a small quantity of hydrogen in the course of a hydrogen line, and supplied to a reversible electrolytic cell 21. The hydrogen manufactured by the electrolytic cell 21 and the unreacted steam are discharged from the outlet port of the electrolytic cell 21, the steam is condensed by a condenser 33 and separated into hydrogen and water. The hydrogen is pressurized by a compressor 34 and returned to a hydrogen tank 30. On the other hand, oxygen system is supplied to the electrolytic cell 21 in a fixed flow rate. The flow rate is increased in the electrolytic cell 21 outlet port at electrolysis, and the flow rate is reduced in the cell 21 outlet port lower than in the inlet port at generation. Thus, in both electrolytic mode and generating mode, hydrogen, oxygen and steam absolutely follow the same route.
