This power adjustment system is provided with: a fuel cell that is connected to a load; a converter for the fuel cell, said converter being connected between the fuel cell and the load and converting the output voltage of the fuel cell at a prescribed requested voltage ratio; a battery that is connected to the load in parallel to the fuel cell and is a different power supply source from the fuel cell; a converter for the battery, said converter being connected between the battery and the load and converting the output voltage of the battery at a prescribed requested voltage ratio; a current bypass path that bypasses the converter for the fuel cell and links the fuel cell and the load; an AC voltage applying unit that applies an AC voltage signal to the output side of the converter for the fuel cell; and an internal condition estimation unit that estimates the internal condition of the fuel cell on the basis of a prescribed physical quantity when the AC voltage signal is applied by the AC voltage applying unit. |
