Abstract
An electronic apparatus includes a fuel cell device, an image pickup device, a lens unit, a temperature sensor, and a system controller. The electronic apparatus is mobile and held in a user's hand while being operated. The fuel cell device controls electrical power generation. The image pickup device is positioned relative to the fuel cell device and converts an image into an image pickup signal. The lens unit provides the image to the image pickup device. The temperature sensor obtains a temperature from the lens unit. The system controller controls operation of the fuel cell device based on the temperature. A secondary battery stores electrical power generated by the fuel cell device. When the temperature exceeds a reference temperature and a remaining power level in the secondary battery is equal to a reference power level, the system controller halts a moving supply of fuel to the fuel cell device.
