    • A control device receives an output signal from a liquid level sensor disposed in an anode chamber. This output signal indicates whether the liquid level of the electrolytic bath in the anode chamber is higher than a reference level. When the liquid level of the electrolytic bath in the anode chamber is higher than the reference level, the control device increases, by a prescribe value, the frequency of a compressor driving voltage that is generated in an inverter circuit. This increases the rotational speed of a motor in the compressor, increases the discharge pressure of hydrogen gas being discharged from the compressor, and decreases the pressure inside the cathode chamber. As a result, the liquid level of the electrolytic bath in the cathode chamber rises, and the liquid level of the electrolytic bath in the anode chamber falls below the reference level.
    • 控制装置从设置在阳极室中的液位传感器接收输出信号。 该输出信号表示阳极室中的电解液的液面高于参考水平。 当阳极室中的电解液的液位高于参考水平时,控制装置以规定值增加在逆变器电路中产生的压缩机驱动电压的频率。 这增加了压缩机中的电动机的转速,增加了从压缩机排出的氢气的排出压力,并降低了阴极室内的压力。 结果,阴极室中的电解液的液面升高,阳极室中的电解液的液面低于基准水平。
