PORTABLE COMPUTER CPAPBLE OF USING FUEL CELL

摘要

PURPOSE: A portable computer including a fuel cell is provided to efficiently manage power of the portable computer including the fuel cell to receive fuel from the outside. CONSTITUTION: The first fuel valve(28a) supplies the fuel to the fuel cell(27) from the outside of the portable computer. A signal sensor(24) senses an external fuel supply signal from the first fuel valve. A controller(23) makes a CPU operated in a high performance mode based on the sensed external fuel supply signal. The second fuel valve(28b) supplies the fuel to the fuel cell from a fuel cartridge in the fuel cell. The signal sensor senses an internal fuel supply signal from the second fuel valve and the controller makes the CPU operated in a low power consumption mode based on the sensed internal fuel supply signal.
