FUEL CELL SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240347747 titled 'FUEL CELL SYSTEM

Simplified Explanation: The control device of a fuel cell system detects abnormalities in the opening and closing of valves based on pressure decrease rates during different control scenarios.

The control device compares the pressure decrease rates of a first valve and a second valve to determine abnormalities.
The first pressure decrease rate is measured when the first valve is opened while the second valve is closed.
The second pressure decrease rate is measured when the second valve is opened while the first valve is closed.

Key Features and Innovation:

Detection of valve abnormalities based on pressure decrease rates.
Comparison of pressure decrease rates during different control scenarios.
Prevents potential malfunctions in the fuel cell system.

Potential Applications:

Fuel cell systems in automotive vehicles.
Industrial power generation systems.
Portable fuel cell devices.

Problems Solved:

Early detection of valve abnormalities.
Prevention of system malfunctions.
Improved safety and efficiency of fuel cell systems.

Benefits:

Enhanced reliability of fuel cell systems.
Reduced maintenance costs.
Increased lifespan of system components.

Commercial Applications:

Automotive industry for electric vehicles.
Energy sector for power generation.
Consumer electronics for portable fuel cell devices.

Questions about Fuel Cell System Control Device: 1. How does the control device determine abnormalities in valve operation? 2. What are the potential implications of early detection of valve abnormalities in fuel cell systems?

Frequently Updated Research: Ongoing research in fuel cell technology focuses on improving efficiency and durability of fuel cell systems, including control devices for valve operation.

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.
