Abstract
An electronic apparatus, such as a camera, is configured to be driven by a fuel cell. The fuel cell includes a fuel unit and a power generation unit. The fuel unit is configured to store fuel, and the power generation unit is configured to generate electric power with at least one power generation cell by receiving fuel from the fuel unit. The camera includes a fuel cell storage section configured to store both the fuel unit and the power generation unit, and a power generation unit determination device configured to determine an output characteristic of the power generation unit. A memory in the power generation unit holds information on one of a voltage, an electric current, and an internal resistance. This information is read by a system controller in the camera.
