Title:
FUEL CIRCULATION TYPE FUEL CELL SYSTEM
Document Type and Number:
Japanese Patent JP3659582
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel circulation type fuel cell system which resolves temporal reduction of a circulation amount of hydrogen in a hydrogen circulation system, when a quick acceleration and deceleration instruction is given to a fuel cell.
SOLUTION: This fuel circulation type fuel cell system comprises a fuel cell stack 1 for generating electricity with fuel and oxidizer supplied; a fuel circulation passage 6 for resupplying to the fuel cell stack 1 again with fuel discharged from the fuel cell stack 1; a fuel pump 3 disposed in the fuel circulation passage 6 for supplying new fuel to the fuel circulation passage 6 and for circulating the fuel in the fuel circulation passage 6 with a given circulation amount; and an ECU 4 for issuing an output instruction value to the fuel cell stack 1 and for controlling the circulation amount of the fuel in the fuel circulation passage 6, depending on the output instruction value.
