Title:
FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/173620
Kind Code:
A1
Abstract:
This fuel cell system (100) comprises: a fuel cell (13) that generates power using hydrogen gas and oxidant gas; a reformer (11) that generates the hydrogen gas; a combustor (15) that heats the reformer (11); an exhaust passage (17) for the combustion exhaust gas generated by the combustor (15); a CO sensor (19) disposed in the exhaust passage (17); and a controller (32) that monitors the combustion state in the combustor (15) based on the detection value of the CO sensor (19). The controller (32) executes a first process for intentionally increasing the CO concentration in the combustion exhaust gas during the power generation period of the fuel cell (13) and inspecting the CO sensor, and executes a second process for causing the power generation amount of the fuel cell (13) to converge with a target value.
