摘要： A fuel cell system that employs a method for determining the potential that a freeze condition will exist after the system is shut-down based on predetermined input, such as ambient temperature, geographical location, user usage profile, date, weather reports, etc. If the system determines that a freeze condition is probable, then the system initiates a purge shut-down of the fuel cell system where water is purged out of the reactant gas flow channels. If the system determines that a freeze condition is unlikely, then it will initiate a normal shut-down procedure without purging the flow channels. The system will then periodically determine if the conditions have changed, and will initiate the purge if a freeze condition subsequently becomes probable.

摘要： A gas flow control system for a fuel cell includes a gas supply and a humidifier. A fuel cell stack includes a cathode flow line with an inlet and an outlet. The inlet of the cathode flow line is connected to the outlet of the humidifier. A combustor includes an inlet that receives gas from the outlet of the cathode flow line. A valve and a bypass line bypass gas around the humidifier and the fuel cell stack to the combustor. The valve is preferably one of a gas restriction valve, a throttle valve, and a directional valve. A gas flow sensor generates a gas flow signal based on gas flowing through at least one of the humidifier, the cathode flow line of the fuel cell stack, and the bypass line. A flow controller that is connected to the gas flow sensor and the valve controls the valve based on the gas flow signal.
