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.

An electronic apparatus configured to be driven by a fuel cell, the fuel cell including a fuel unit and a power generation unit, the fuel unit being configured to store fuel, the power generation unit being configured to generate electric power with at least one power generation cell by receiving fuel from the fuel unit, the electronic apparatus comprising:
- a fuel cell storage section configured to store both the fuel unit and the power generation unit,
- wherein the fuel cell storage section is adapted to store a fuel unit selected from a group of same type of fuel units, but wherein each fuel unit from the group has at least one of a different fuel capacity or physical packaging size,
- wherein the fuel cell storage section is further adapted to store a power generation unit selected from a group of same type of power generation units, but wherein each power generation unit from the group has at least one of a different power output characteristic or physical packaging size, and
- wherein the selected fuel unit and power generation unit are further adapted to be integrated together and combined to form the fuel cell;
- and
- a power generation unit determination device configured to determine an output characteristic of the power generation unit,
- wherein the power generation unit determination device determines output characteristics of the fuel generation unit making up the fuel cell stored in the storage section.
