Patent ID: 8877396

Claim:
A fuel cell system that is mounted on a moving body including a power unit and includes a fuel cell that supplies electric power to the power unit, comprising: a temperature detection unit that detects a temperature of the fuel cell and outputs the detected results; an output prediction unit that predicts an output according to the temperature and a current of the fuel cell and outputs the predicted results; an operation state quantity setting unit that sets an operation state quantity according to the temperature and the current of the fuel cell; a control unit that outputs a command value that indicates operation of the power unit according to a power demand with respect to the power unit; and a deterioration state detection unit that detects a deterioration state of the fuel cell and outputs the detected results, wherein the control unit sets a required fuel cell output what the fuel cell requires according to a present power demand and causes the output prediction unit to predict a current according to the required fuel cell output and the temperature of the detected results that are output from the temperature detection unit, wherein the control unit causes the operation state quantity setting unit to set an operation state quantity according to the current of the predicted results that are output from the output prediction unit and the temperature of the detected results that are output from the temperature detection unit, based on a predetermined operation state quantity map, stored in the operation state quantity setting unit, the predetermined operation state quantity map showing a relationship between the temperature, the predicted current of the fuel cell and the operation state quantity, and wherein the output prediction unit corrects the output state map according to the deterioration state of the detected results that are output from the deterioration state detection unit.
