摘要： PROBLEM TO BE SOLVED: To provide a solar battery power supply device which only interrupts the charging of a battery and, at the same time, supplies electric power to a load from the battery without instantaneous interruption depending upon the generated voltage of a solar battery power generator or the ambient temperature of the battery. SOLUTION: A solar battery power supply device is provided with a voltage comparator 6 which compares the voltage generated from a reference voltage generator 5 with the voltage generated from a solar battery power generator 1 and outputs the compared results and a charging-of-battery interrupting switch 7 which supplies the output of the power generator 1 to a battery 2 so as to charge the battery 2 in accordance with the output signal of the comparator 6. When the voltage generated from the power generator 1 is higher than that generated from the reference voltage generator 5, the overcharging of the battery 2 is prevented while the switch 7 is opened and the output of the power generator 1 is supplied to a load 3.

摘要： PURPOSE:To improve the refrigerating performance per steam quantity to be supplied by providing a condensed water exhausting quantity control means on the condensed water ring water pipeline of an absorbing type refrigerator. CONSTITUTION:The pressure signal of cell cooling water detected by a pressure detecting means 40 is inputted to a controller 42, and compared with a preliminarily inputted pressure set value of cell cooling water. The opening signal of a condensed water discharge quantity control valve 41 is outputted to eliminate the deviation between the cell cooling water pressure detected by the detecting means 40 and the pressure set value. Consequently, when the pressure of the cell cooling water is lowered, the opening of the control valve 41 is reduced to minimize the condensed water discharge quantity, and the effective condensation heat transfer area of a heat exchanger in the high temperature regenerator 22 of an absorbing type refrigerator is minimized by the condensed water of steam to raise the pressure of the cell cooling water. Contrary to this, when the pressure of the cell cooling water is raised, the opening of the valve 41 is increased, and consequently, the pressure of the cell cooling water is reduced.

摘要： PURPOSE:To follow any sudden change of a load by regularly supplying a fuel necessary for the maximum demand of the load to a fuel cell. CONSTITUTION:A temperature detecting means 9 outputs a flow rate decrease or increase signal to flow rate regulators 8, 15 according to the temperature up or down of a reformer 2 to keep the temperature of the reformer 2 constant. When a load 7 is increased, the flow rate is regulated by a flow rate setter 13 so that the fuel utilizing ratio is about 80% at the maximum demand of the load 7. Since a boiler 11 keeps the pressure by the combustion of the unreacted hydrogen from a fuel cell 1, the output signal of a pressure detecting means 12 is compared with the output signal of the setter 13 by a comparator 14, and the larger output signal of the setter 13 is transmitted to a flow rate regulator 3 to set the fuel flow rate to the set flow rate of the setter 13. Thus, the cell 11 is regularly operated with a fuel utilizing ratio of about 80%, and even when the load 7 is increased, it is within this range. Therefore, the cell 1 can follow even when the load 7 is suddenly changed. The less the load 7, the more the supplied hydrogen quantity to a combustion part 10 is increased.

摘要： PURPOSE:To control a reformer temperature to be constant when both city gas and methanol are used in the case where supply of the city gas is stopped by arranging a reformer combustion use air blower and an air blower rotation control means to control the number of revolutions. CONSTITUTION:When methanol is used as raw material fuel, since a heat quantity of hydrogen fuel gas becomes more surplus than when city gas is used, it is necessary to increase a methanol using time air blowing quantity more than an air blowing quantity of reformer combustion air to a reformer 2 when the city gas is used as the raw material fuel. When a surplus heat quantity in the reformer 2 is increased and a reformer temperature becomes higher than a preset temperature inputted beforehand to a control device 20, the number of revolutions of an air blower is increased and the air blowing quantity is increased by a revolution number control means 16 of a reformer combustion use air blower 40 from the control device 20. When the raw material fuel is switched to the city gas from the methanol to the contrary, it is controlled so as to reduce the air blowing quantity by inverse operation.
