FUEL CELL SYSTEM
Document Type and Number:
Japanese Patent JP2018147850
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell system in which deterioration state of auxiliary equipment can be diagnosed while running a 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 modified fuel gas and an oxidization material, assistant equipment (a fuel gas pump 20, a water pump 28, an air blower 12) for assisting power generation of the cell stack, and a controller 52 for controlling the auxiliary equipment. The controller 52 includes auxiliary equipment deterioration diagnosis means 56 performing deterioration diagnosis of the assistant equipment. The auxiliary equipment deterioration diagnosis means 56 includes auxiliary equipment deterioration gradient value calculation means 78 calculating deterioration progress state of the auxiliary equipment for every interval of the deterioration diagnosis period, auxiliary equipment prediction deterioration value calculation means 80 for calculating the auxiliary equipment prediction deterioration value in the reference life period based on the auxiliary equipment deterioration gradient value, and auxiliary equipment deterioration determination value 82 for determining whether or not deterioration is in progress based on the auxiliary equipment prediction deterioration value.SELECTED DRAWING: Figure 2
