摘要： The moisture state of a fuel cell is determined without causing any variation in the supply state of the reactant gas to be supplied to the fuel cell. An output current control section [[71]] temporarily performs a current sweep while maintaining the amount of oxidant gas to be supplied to the fuel cell. A resistance component calculation section [[72b]] calculates the resistance component in the fuel cell by using an output current value and an output voltage value of the fuel cell being that of when the current sweep is temporarily performed. A moisture content calculation section [[72c]] calculates the moisture content in the fuel cell by using the resistance component. A moisture content determination section [[72d]] determines whether or not the moisture content is equal to or lower than a dry state threshold value. A moisture content increasing processing section [[73]] performs a moisture content increasing process when the moisture content is equal to or lower than the dry state threshold value.

摘要： This fuel cell system is for suppressing a backflow of water from an exhaust pipe outlet that discharges a reactant-off gas, without decreasing the performance and fuel consumption of a fuel cell, the exhaust pipe being configured to switch between a main discharge pipe and a sub discharge pipe by a switching means to discharge the reactant-off gas. The sub discharge pipe includes a rising gradient portion formed to incline upwards above a gradient of the main discharge pipe and a falling gradient portion formed to incline downwards at the downstream of the rising gradient portion. The switching valve switches to allow the reactant-off gas to be discharged from the main discharge pipe if an amount of reactant-off gas to be discharged is equal to or above a threshold value of an amount of discharge, and allow the reactant-off gas to be discharged from the sub discharge pipe if the amount of reactant-off gas to be discharged is below the threshold value of the amount of discharge.

摘要： A fuel cell system includes: a fuel cell; a secondary cell that receives and stores surplus power by which output of the fuel cell is greater than power demanded of the system if the output is so, and that compensates for shortfall by which the output of the fuel cell is less than the power demanded of the system if the output is so; a voltage measurement portion that measures voltage of the fuel cell; a current measurement portion that measures current of the fuel cell; and a control portion that performs a control such that the voltage of the fuel cell does not exceed or equal a pre-set high-potential avoidance voltage. If a current-voltage characteristic of the fuel cell declines by at least a pre-determined amount from an early-period level, the control portion re-sets the high-potential avoidance voltage to a value that is smaller than an early-period set value.
