燃料電池システム
Document Type and Number:
Japanese Patent JP6817112
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell system capable of diagnosing the deterioration state of a cell stack, while running the fuel cell system.SOLUTION: A fuel cell system includes a reformer for modifying fuel gas, a cell stack performing power generation by oxidization and reduction of the fuel gas modified by the reformer and an oxidation material, and a controller 52 for controlling a fuel gas pump 20 and the like. The controller 52 includes stack deterioration diagnosis means 58 performing deterioration diagnosis of the cell stack. The stack deterioration diagnosis means 58 includes stack deterioration gradient value calculation means 78 for calculating deterioration progress state (stack deterioration gradient value) of the cell stack every deterioration diagnosis period, a stack prediction deterioration value calculation means 80 for calculating a stack prediction deterioration value based on the stack deterioration gradient value, and stack deterioration determination means 82 for determining deterioration progress based on the stack deterioration prediction value.SELECTED DRAWING: Figure 2
