<p>A fuel cell system includes a fuel cell (24), a reforming portion (23), a combusting portion (26), an exhaust heat recovery system (30), a detection sensor (24d, 26b1, 26b2, 32b, 32c, 32d, 41 b, 42c, 44b, 42b, 41c, 44c), and a control device (60). The control device (60) includes a sensor malfunction determination device (step 106, step 108, 61) determining whether or not an output signal of the detection sensor is out of a first determination range for a first determination time (TM1) or longer, a state error determination device (steps 112 to 118, 62) determining whether or not a state of a physical quantity is in an error state on a basis of whether or not the output signal is out of a second determination range for a second determination time (TM2) or longer, and a storage device (step 120, 65) storing a determination result from each of the sensor malfunction determination device and the state error determination device.</p> |
