CELL UNIT HAVING TWO TYPES OF FUEL CELLS, ELECTRONIC APPARATUS HAVING FUEL CELL, AND PROVIDING METHOD OF ELECTRIC POWER

Document Type and Number:

WIPO Patent Application WO2004032269

Kind Code:

A3

Abstract:

An electronic apparatus has a first fuel cell capable of generating first electric power, a second fuel cell capable of generating second electric power less than the first electric power, a switching circuit coupled to the first fuel cell and the second fuel cell, and an electronic device coupled to the switching circuit. The electronic device is operable with one of the first electric power and the second electric power, depending on the electric power demand of the electric device.
