Title:
Solid oxide type fuel cell system
Document Type and Number:
Japanese Patent JP6183774
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a solid oxide type fuel battery system which is arranged so that the fuel electrode oxidation and the air electrode reduction of a fuel battery cell can be avoided by shutdown stop.SOLUTION: A solid oxide type fuel battery system (1) comprises: a fuel battery module (2); a fuel-supply device (38); a water-supply device (28); an air-supply device (45); a reformer (20); a temperature detection sensor (142) for detecting a temperature of a fuel battery cell stack; a shutdown-stop circuit (110a); and an exhaust-control circuit (110d). The shutdown-stop circuit executes a shutdown stop on condition that the fuel battery cell stack is put at an oxidation-suppressing temperature or higher. The exhaust-control circuit activates the air-supply device after shutdown stop, thereby executing exhaust control for exhausting air remaining on the side of an air electrode in the fuel battery module according to a temperature detected by the temperature detection sensor.
