    • PURPOSE:To supply high temperature abundant steam outside of a system by a compact power generation device. CONSTITUTION:A battery cooling water circulating system supplies battery cooling water to the cooling water inlet piping side connected to a cooler 1c in a fuel cell body, and supplies the battery cooling water taken out of a cooling water outlet piping to a steam separator 3 to separate it into steam and water, and supplies the separated water again to the cooling water inlet piping side. A condenser-evaporator 23 is arranged in a steam utilizing system, and heat is exchanged between steam to be supplied to the high temperature heating side 23A and water to be supplied to the low temperature side 23B to be heated, and high temperature heating side steam is turned into condensed water, and water to be supplied to the low temperature side to be heated is turned into steam. The steam separated from the steam separator 3 is supplied to the high temperature heating side of the condenser-evaporator 23, and the condensed water is returned to the battery cooling water circulating system. Water utilized by a steam utilizing equipment 9 is supplied to the low temperature side to be heated of the condenser-evaporator, and generated steam is supplied to the steam utilizing equipment 9.

    • PURPOSE:To uniformly hold the coarse and dense state of steel wool by providing a plurality of lattice like demarcating members dividing steel wool in the flow direction of the discharge gas from a battery and providing support members supporting the demarcating members so as to hold the predetermined positional relation between them. CONSTITUTION:A main body 1 having a gas inlet 2 provided to the bottom part thereof and a gas outlet 5 provided to the upper part thereof is arranged and steel wool 10 is laminated to the flow path region ranging from the gas inlet 2 of the main body 1 to the gas outlet 5 thereof so as to remove phosphoric acid from the discharge gas of a battery guided into the main body 1. A plurality of lattice like demarcating members 7 dividing the steel wool 10 in the flow direction of the discharge gas of the battery are arranged and supported by support members 8 so as to hold predetermined positional relation. As a result, the coarse and dense state of the steel wool can be uniformly held and the magnification of the variation width of pressure loss can be held small.

    • PURPOSE:To effectively prevent the abnormal rise of an output power source voltage when the circuit becomes abnormal by controlling the transistor current of a photocoupler in response to the output power source voltage. CONSTITUTION:When a switch S is closed so that a transistor Q1 becomes ON, a condenser C4 starts charging by a coil N5. A transistor Q3 is turned ON at this time point, the transistor current of a photocoupler PC increases, and the transistor Q2 is not turned ON until the current flowed to the resistor R3 becomes considerably large. Accordingly, the conversion energy through the transformer T is large. Thereafter, when the output gradually increases, the current of the transistor Q3 decreases, the transistor current of the photocoupler PC thus decreases, thereby early turning the transistor Q2 ON and reducing the switching power.
    • 目的:通过根据输出电源电压控制光电耦合器的晶体管电流,有效防止电路变得异常时输出电源电压的异常上升。 构成:当开关S闭合以使晶体管Q1导通时,电容器C4通过线圈N5开始充电。 晶体管Q3在该时间点导通,光耦合器PC的晶体管电流增加,并且晶体管Q2在导通到电阻器R3的电流变得相当大之前不会导通。 因此,通过变压器T的转换能量大。 此后,当输出逐渐增加时,晶体管Q3的电流减小,因此光电耦合器PC的晶体管电流减小,从而提前使晶体管Q2导通并降低开关功率。

    • PURPOSE:To detect the time for which an AC adapter has been operated by detecting a DC current, which must be supplied to an external equipment, and counting a supply or non-supply time of DC current to the external equipment based on whether this DC current is provided or not. CONSTITUTION:In the case that a built-in battery 9 of an electronic equipment 7 run out a power supply plug 2 of an AC adapter is connected to a receptacle of AC100V, and a connector 6a of the AC adapter 1 is connected to a connector 6b of the electronic equipment 7. Then, power of AC100V is converted into power of DC12V by a transformer rectifying part 3, and the power of DC100V is as a driving power supply to a time counting part 5. Further, a DC current is supplied to the built-in battery 9 of the electronic equipment 7, and the built-in battery 9 is charged to supply the DC current to a main circuit part 7. The time counting part 5, when the DC current supplied to the built-in battery 9 of the electronic equipment 7 is detected by a current detector 4, starts time counting to display the counted time.
