Abstract: A microcomputer of a fuel cell unit controls the output power of a DMFC at two stages in a High mode and in a Low mode by driving of an auxiliary machine. When an output value of a DC/DC converter exceeds a predetermined value, the microcomputer decides a rechargeable cell connected to one diode of a diode OR circuit of an electronic apparatus side with the other diode connected to the converter as being a near-full charged level and drives the auxiliary machine so as to lower an output power from a High mode to a Low mode. When, after this, a predetermined time is elapsed, the microcomputer decides the residual amount of the rechargeable cell as being lowered down to a predefined value and drives the auxiliary machine so as to return the output power from the Low mode to the High mode.
