ABSTRACT:
A fuel cell unit for supplying electric power to an electronic apparatus includes a DMFC that generates electric power using methanol as fuel. A microcomputer examines whether or not the fuel cell unit has been installed in the electronic apparatus. When the fuel cell unit has been installed in the electronic apparatus, the microcomputer visually informs the user, using LEDs, of the operating state of the DMFC detected by various sensors, including an installation and removal sensor, a liquid level sensor, a temperature sensor, and an acceleration sensor.
