Abstract
Disclosed is a fuel cell power supply device in which an I-V characteristics estimating unit estimates output current/voltage characteristics (I-V characteristics) of a fuel cell by substituting a linear function (V=F(I)) in which a gradient indicates an internal resistance of the fuel cell and an interception of an axis representing a voltage (V) indicates an open-circuit voltage of the fuel cell calculated by a fuel cell open-circuit voltage calculator for the I-V characteristics. On the basis of the I-V characteristics of the fuel cell estimated by the I-V characteristics estimating unit, a requested output voltage determining unit and a requested output current determining unit determine a requested output voltage and a requested output current, respectively, which are needed to obtain a target total electric energy.
