摘要： 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.

摘要： PURPOSE:To achieve power generation with high efficiency, whenever necessary, by supplying steam to an electrolytic-power generating means. CONSTITUTION:At the time of storing electric power in a reversible type solid oxide electrolyte cell 1, water is supplied from a water tank 2 by a pump 3 through regenerative heat exchangers 4C, 4D, 4A, 4B and a heater 6, to be thus turned into steam. A DC current is supplied to an electrode so that oxygen and hydrogen are separated from each other. Oxygen is stored in an oxygen tank 8 through a compressor 7 while hydrogen is supplied to a hydrogen tank 5 filled with a hydrogen storage alloy. Water supplied from the tank 2 is heated by oxygen in the exchangers 4B, 4D. The water is heated by hydrogen in the exchangers 4A, 4C so that energy can be effectively recovered. In generating power, oxygen flows reversely from the tank 8, and hydrogen is discharged reversely from the storage alloy of the tank 5, thus producing steam in the cell 1. Accordingly, an oxygen ion passes an electrolyte, thereby generating a current, which is taken out as electric power. Consequently, power generation can be performed with high efficiency.

摘要： PURPOSE:To take out a true pressure pulsation signal, by subtracting the vibration detection signal taken out by a vibration detection sensor from the pressure pulsation measuring signal taken out by a pressure pulsation measuring sensor. CONSTITUTION:A pressure pulsation measuring sensor 4 is mounted to the opening part of a boss 3 and a vibration detection sensor 5 is connected to the case of the pressure pulsation measuring sensor 4 by a clamp 6. Because the diaphragm part of the vibration detection sensor 5 is hollow, said sensor 5 does not respond to pressure pulsation and picks up only the pressure pulsation measuring sensor 4. The output signals from both sensors 4, 5 are respectively amplified by amplifiers 7, 8. These two amplified signals are applied to a subtractor 9 and the output signal of the vibration detection sensor 5 is subtracted from the output signal of the pressure pulsation measuring sensor 4 to obtain a true pressure pulsation signal from which the piping vibration component is removed.
