Title:
Solid oxide type fuel cell system
Document Type and Number:
Japanese Patent JP6183775
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 for detecting a temperature of a fuel battery cell stack; a shutdown-stop circuit; and a before-stop processing circuit. The shutdown-stop circuit executes a shutdown stop for stopping fuel supply and power generation when being put in the condition of an oxidation-suppressing temperature or higher. The before-stop processing circuit executes a before-stop process for lowering the temperature of the fuel battery cell stack. The before-stop processing circuit executes different before-stop processes according to the temperature of the fuel battery cell stack before the shutdown stop.
