Abstract
To give a guideline associated with control content required to use a fuel cell as a power source in various kinds of electronic equipment, and perform appropriate power management according to loads.
A notebook personal computer includes a hybrid pack (10) which has a battery (11) serving as a secondary battery, a battery protection IC (12) for controlling this battery (11), a fuel cell (13) for causing a predetermine fuel and air to electrochemically react with each other so as to cause a power generating unit to generate power, and a fuel cell controller (14) for controlling this fuel cell (13), and a computer body (20) at least having a CPU (21) for executing various processes and consuming power. In the hybrid pack (10), the battery protection IC (12) and the fuel cell controller (14) mutually transfer at least remaining battery power information indicative of the amount of power remaining in the battery (11) and fuel cell status information indicative of a status of the fuel cell (13), to each other via a bus (30).
