FUEL-CELL SYSTEM WITH PROTECTION FROM ICING

A fuel-cell system is proposed, comprising at least one fuel cell, an oxidant line, a hydrogen line, an exhaust-gas line, a control unit, and at least one electrically controllable valve, which is coupled to the control unit and is connected to one from among the oxidant line, the hydrogen line, and...

More Information
Summary:A fuel-cell system is proposed, comprising at least one fuel cell, an oxidant line, a hydrogen line, an exhaust-gas line, a control unit, and at least one electrically controllable valve, which is coupled to the control unit and is connected to one from among the oxidant line, the hydrogen line, and the exhaust-gas line. The fuel-cell system is distinguished in that the control unit is designed to activate the at least one valve in a pulsating or oscillating manner, at least during a first time interval, such that the at least one valve is prevented from remaining in a stationary state and seizing up by icing during the first time interval.
