FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18585561 titled 'FUEL CELL SYSTEM
Simplified Explanation:
The control device of a fuel cell system detects abnormalities in the opening and closing of valves by comparing pressure decrease rates when different control actions are executed.
- The device compares the pressure decrease rate when the first valve is opened while the second valve is closed (first control) with the pressure decrease rate when the second valve is opened while the first valve is closed (second control).
- Abnormalities in valve operations are determined based on these pressure decrease rates, indicating potential issues with the valves.
- This system helps ensure the proper functioning of valves in a fuel cell system, enhancing overall performance and safety.
Key Features and Innovation:
- Comparison of pressure decrease rates to detect abnormalities in valve operations.
- Differentiation between first and second control actions to assess valve performance.
- Enhances safety and efficiency of fuel cell systems by detecting valve abnormalities promptly.
Potential Applications:
- Fuel cell systems in automotive vehicles.
- Industrial fuel cell power plants.
- Portable fuel cell devices for various applications.
Problems Solved:
- Early detection of valve abnormalities.
- Prevention of potential malfunctions in fuel cell systems.
- Improved safety and performance of fuel cell systems.
Benefits:
- Enhanced safety in fuel cell operations.
- Increased efficiency and reliability of fuel cell systems.
- Cost savings through early detection and prevention of valve issues.
Commercial Applications:
The technology can be applied in various industries such as automotive, power generation, and portable electronics, where fuel cell systems are used. The early detection of valve abnormalities can prevent costly malfunctions and downtime, making it a valuable asset for companies relying on fuel cell technology.
Questions about Fuel Cell Valve Control:
1. How does the control device determine abnormalities in valve operations? 2. What are the potential implications of early detection of valve issues in fuel cell systems?
Original Abstract Submitted
A control device of a fuel cell system determines opening-closing abnormality of a first valve and a second valve based on a comparison between a first pressure decrease rate and a second pressure decrease rate, the first pressure decrease rate being a decrease rate of a pressure detection value of a pressure sensor when a first control is executed, the first control being a control in which the first valve is opened in a state where the second valve is closed, the second pressure decrease rate being a decrease rate of the pressure detection value of the pressure sensor when a second control is executed, the second control being a control in which the second valve is opened in a state where the first valve is closed.
