A charger which can charge a secondary battery suitably with a simple device without particularly requiring fuel supply control, and in which overload to a fuel cell is hard to occur. The charger comprises fuel supply means (10), a fuel cell (FC) which is supplied with fuel from the fuel supply means (10) to generate and output electricity, a DC voltage conversion circuit (20) for converting the output voltage from the fuel cell (FC) into a predetermined voltage and outputting the converted voltage, an output section (30) connected electrically with one output from the DC voltage conversion circuit (20) in order to output power for charging, a current control circuit (40) interposed between the other output from the DC voltage conversion circuit (20) and the output section (30) and controlling the output current from the output section (30) so as not to exceed a predetermined current value, and set current alteration means (60) for varying the set current value of the current control circuit (40) such that the variation pattern of fuel consumption approaches the variation pattern of fuel supply to the fuel cell (FC), |
