Abstract:
A fuel cell system acquires an operation state of a fuel cell and estimates an IV characteristic that indicates a relationship between a current and a voltage in the fuel cell. At least one of a resistance overvoltage, an activation overvoltage, a current-voltage hysteresis and a concentration overvoltage of the fuel cell is determined from the operation state of the fuel cell, and the IV characteristic is estimated based on the determined result.
