An improved fuel processor for fuel cells is provided whereby the startup time of the processor is less than sixty seconds and can be as low as 30 seconds, if not less. A rapid startup time is achieved by either igniting or allowing a small mixture of air and fuel to react over and warm up the catalyst of an autothermal reformer (ATR). The ATR then produces combustible gases to be subsequently oxidized on and simultaneously warm up water-gas shift zone catalysts. After normal operating temperature has been achieved, the proportion of air included with the fuel is greatly diminished.

When a microcomputer does not charge an electric storage device, the microcomputer activates at an interval set based on a timer set value and determines whether an electric power voltage generated by a solar cell is equal to or higher than an electric power generation determination threshold. When the generated electric power voltage is lower than the electric power generation determination threshold, the microcomputer turns to a sleep state after increasing the timer set value by an addition set value while prohibiting charging the electric storage device. When the generated electric power voltage is equal to or higher than the electric power generation determination threshold and a generated electric power amount is equal to or larger than an electric power generation determination threshold, the microcomputer starts charging the electric storage device so the electric power device can be appropriately charged with an electric power generated by the solar cell.
