1. A control device for controlling an electric power supply device configured to supply electric power to a work machine,
the electric power supply device including:
a fuel cell;
a utility connecting section for transferring a utility to be utilized for an operation of the fuel cell between the work machine and the electric power supply device,
the control device comprising:
a rated capability obtaining section for obtaining information indicating a rated value of a capability with which the work machine supplies the utility to the fuel cell in response to the electric power supply device being mounted in the work machine or the electric power supply device being able to utilize the utility, and
an operating condition determining section for determining an operating condition of the electric power supply device based on the rated value, wherein
when the rated value of the capability with which the utility is supplied satisfies a predetermined condition, the operating condition determining section (i) sets a maximum value of an output electric power of the fuel cell to a value smaller than a rated value of an output electric power of the fuel cell, (ii) sets a maximum value of an output electric current of the fuel cell to a value smaller than a rated value of an output electric current of the fuel cell, or (iii) sets a maximum value of an output rate of the fuel cell to a value smaller than a rated value of an output rate of the fuel cell.
