Title:
燃料電池システム、その運転方法及びその構成方法
Document Type and Number:
Japanese Patent JP6475023
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress the influence of dispersion in performance among plural fuel batteries which are connected to one another in parallel.SOLUTION: Three fuel battery cells 18A to 18c are electrically connected to one another in parallel by electrical wires 50, 52, and successively connected in series in the order of the fuel battery cells 18A, 18B, 18C through a fuel gas pipe 30 and fuel electrode exhaust gas pipes 36, 40 so as to supply fuel in series. A fuel controller 16 can control the fuel supply amount to the fuel battery cell 18a, and a power conditioner 20 can control the magnitude of the total current corresponding to added current of the fuel battery cells 18A to 18C. An operation controller 22 controls the magnitude of the total current flowing in the electrical wires 50, 52 according to a request output, and controls the fuel supply amount to the fuel battery cell 18A at the most upstream side to the fuel amount corresponding to the total current.SELECTED DRAWING: Figure 4
