<P>PROBLEM TO BE SOLVED: To provide a fuel cell power blending device which can control fuel cell output power easily and dynamically. <P>SOLUTION: The fuel cell power blending device includes a fuel cell battery unit, a fuel cell voltage conversion unit, a sensor unit, a secondary battery and a charging unit. The power output side of the secondary battery is connected to the power output side of the fuel cell voltage conversion unit, and the characteristics of power to be fed for charging the secondary battery are determined by the charging unit according to an electric signal generated by the sensor unit. By using the transmission power of the fuel cell, the sensor unit adjusts a setting voltage value on the output side of the fuel cell voltage conversion unit and a setting voltage of the secondary battery, and at the same time, according to a difference between both setting voltage values, the charging unit charges the secondary battery unit or discharges the secondary battery, so that the fuel cell battery unit generates power at constant power level. <P>COPYRIGHT: (C)2009,JPO&INPIT |
