Fuel cell power supply device |
摘要 |
Disclosed is a fuel cell power supply device which can accurately determine a requested output current of a fuel cell depending on an electric energy requested by a load even if output current/voltage characteristics of the fuel cell change. A power supply management control unit 14 has an I-V characteristics estimating unit 52 for estimating 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 (Rfc) of the fuel cell and an interception of an axis representing a voltage (V) indicates an open-circuit voltage (Vfc_o) of the fuel cell calculated by a fuel cell open-circuit voltage calculator 51 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 52, a requested output voltage determining unit 53 and a requested output current determining unit 54 determine a requested output voltage (Vfc_REQ) and a requested output current (Ifc_REQ), respectively, which are needed to obtain a target total electric energy (Psys). <IMAGE> |
