A method of operating a fuel cell system having a fuel cell stack and a humidifier is disclosed. The method includes directing at least a portion of the reactant gas through the reactant chamber of the humidifier, directing at least a portion of the exhaust gas through the exhaust chamber of the humidifier, determining the first pressure drop of the exhaust gas directed through the exhaust chamber, determining the first pressure drop limit of the exhaust gas directed through the exhaust chamber, and bypassing the remainder portion of the exhaust gas from the exhaust gas outlet around the exhaust chamber through the exhaust bypass passageway so that the first pressure drop does not exceed the determined first pressure drop limit. |
