ABSTRACT:
A fuel cell1and an electric double-layer capacitor2are parallelly arranged for a power supply. A DC/DC converter3steps up voltage of the fuel cell1and the electric double-layer capacitor2, to thereby output power. An output switch5is disposed on an output pathway of the DC/DC converter3. By controlling the output switch5with a control IC4, output power can be switched on and off. When there is a fuel shortage or abnormality in the fuel cell1, the control IC4controls the output switch5, to thereby intermittently alter the output power. With this configuration, when the power supply is used for a mobile telephone as a portable electronic device connected thereto, a user can confirm whether there is a fuel shortage or a fuel cell abnormality by checking of blinking state of a charge pilot lamp of the mobile telephone.
