FUEL CELL SYSTEM AND CONTROL METHOD OF FUEL CELL SYSTEM

摘要

An object is to provide a technique that a current state of a fuel cell may be detected more accurately. A fuel cell system includes a controller, a fuel cell, and an impedance measurer that may measure an impedance of the fuel cell. The controller obtains a first impedance value that expresses the impedance of the fuel cell in a predetermined state, acquires a second impedance value that expresses the impedance of the fuel cell that is measured by the impedance measurer during operation control of the fuel cell, and performs operation control of the fuel cell using the first impedance value and the second impedance value.

1. A fuel cell system, comprising:
a fuel cell; an impedance measurer that measures an impedance of the fuel cell; and a controller for performing an operation control of the fuel cell, wherein the controller obtains a first impedance value that expresses the impedance of the fuel cell in a predetermined state, acquires a second impedance value that expresses the impedance of the fuel cell that is measured by the impedance measurer during the operation control of the fuel cell, and performs operation control of the fuel cell using the first impedance value and the second impedance value.
