Abstract

PURPOSE:To easily control hydrazine concentration within a preset range by intermittently supplying the concentration sensor power with a rotary switch in which both the conductive and insulating sections are provided in a body of rotation. CONSTITUTION:The anolite which is the mixed aqueous solution of hydrazine and electrolyte is stored in the tank 4 and is supplied to the main battery 1 through the circulating channel 5 with the pump 6. Since hydrazine is consumed, the hydrazine concentration in the anolite 14 is detected in Point B by means of the voltage change of the sensor 9 which supplies constant current with the constant current circuit 15. The hydrazine supplying valve 11 is opened and closed through the driving circuit 21 with the control circuit 10 and is controlled. In addition, power surrent pulses are supplied to the sensor 9 through the rotary switch 16 in which both the conductive and insulating sections 18 and 18 are provided around a body of rotation. This enables the hydrazine concentration in the anolite to easily be controlled within a preset range and stable electrical energy to be removed from the main battery.
