FUEL-CELL SYSTEM WITH PROTECTION FROM ICING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18260631 titled 'FUEL-CELL SYSTEM WITH PROTECTION FROM ICING
Simplified Explanation
The patent application describes a fuel-cell system that includes a control unit designed to activate valves in a pulsating or oscillating manner to prevent them from seizing up due to icing.
- The fuel-cell system comprises 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.
- The control unit activates the valves in a pulsating or oscillating manner during a first time interval to prevent them from seizing up by icing.
- The valves are connected to either the oxidant line, the hydrogen line, or the exhaust-gas line.
- Potential Applications
- Automotive industry for fuel cell vehicles
- Power generation for stationary fuel cell systems
- Problems Solved
- Preventing valves from seizing up due to icing
- Ensuring continuous operation of the fuel-cell system
- Benefits
- Improved reliability and efficiency of the fuel-cell system
- Extended lifespan of the valves
- Reduced maintenance costs and downtime.
Original Abstract Submitted
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.
