Abstract
A fuel cell system comprising: a fuel cell, a fuel gas supplier configured to supply fuel gas to an anode of the fuel cell, an oxidant gas supplier configured to supply oxidant gas to a cathode of the fuel cell, a humidity adjuster configured to adjust a relative humidity of the fuel gas and a relative humidity of the oxidant gas, and a controller, wherein the controller detects the relative humidity of the fuel gas at an anode inlet of the fuel cell, and the controller detects the relative humidity of the oxidant gas at a cathode outlet of the fuel cell, and wherein, based on detection results, the controller controls the humidity adjuster so that the relative humidity of the fuel gas at the anode inlet is higher than the relative humidity of the oxidant gas at the cathode outlet.
