ABSTRACT:
In equipment with a built-in fuel cell, there are provided a plurality of secondary cells, and each of the secondary cells has a first state in which an electric power is supplied to a load within the equipment, and a second state in which the electric power that is supplied from the fuel cell is charged, and the first state and the second state is selectively used. The present invention can provide the fuel cell-carried equipment that stably operates due to a power system on which a fuel cell and plural secondary cells are mounted.
