METHOD FOR DIAGNOSING VALVE FAILURE OF FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18080438 titled 'METHOD FOR DIAGNOSING VALVE FAILURE OF FUEL CELL SYSTEM
Simplified Explanation
The patent application proposes a method for diagnosing valve failure in a fuel cell system. The method involves using a controller to determine a target pressure for diagnosing valve failure based on real-time atmospheric pressure data. The fuel supply valve in the hydrogen supply line is controlled to open in order to reach the target pressure on the stack anode-side.
- The method involves determining a target pressure for diagnosing valve failure based on atmospheric pressure data.
- The fuel supply valve in the hydrogen supply line is controlled to open and reach the target pressure on the stack anode-side.
- An integrated discharge valve installed at a water trap is opened when the stack anode-side pressure reaches the target pressure.
- The time passed after the opening is counted to determine if the integrated discharge valve fails.
- The determination of valve failure is based on the time, stack anode-side pressure, and atmospheric pressure.
Potential Applications
- This method can be applied in fuel cell systems used in various industries such as automotive, aerospace, and power generation.
- It can be used in the maintenance and monitoring of fuel cell systems to detect valve failures and prevent potential issues.
Problems Solved
- Valve failures in fuel cell systems can lead to inefficient operation and potential safety hazards.
- This method provides a reliable and efficient way to diagnose valve failures in real-time, allowing for timely maintenance and prevention of further damage.
Benefits
- The method allows for early detection of valve failures, minimizing downtime and reducing repair costs.
- Real-time monitoring of valve performance helps optimize the efficiency and reliability of fuel cell systems.
- By preventing valve failures, the method enhances the overall safety of fuel cell systems.
Original Abstract Submitted
A method for diagnosing valve failure of a fuel cell system is proposed. The method comprises determining failure diagnosis target pressure from atmospheric pressure that is a real-time sensing value of an atmospheric sensor by means of a controller, controlling opening of a fuel supply valve installed in a hydrogen supply line such that stack anode-side pressure reaches the determined failure diagnosis target pressure by means of the controller, performing control for opening an integrated discharge valve installed at a water trap when the stack anode-side pressure reaches the failure diagnosis target pressure, counting a time passed after the opening, and determining whether the integrated discharge valve fails based on the time, the stack anode-side pressure, and the atmospheric pressure.
