SYSTEM AND METHOD FOR FUEL CELL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240105975 titled 'SYSTEM AND METHOD FOR FUEL CELL

Simplified Explanation

The patent application describes a fuel cell system with an ejector, hydrogen pressure sensor, supply valve, discharge valve, and controller for controlling hydrogen flow in a fuel cell stack.

• The ejector is located in the hydrogen supply line to enhance the flow of hydrogen into the fuel cell stack.
• The hydrogen pressure sensor measures the pressure of hydrogen coming from the hydrogen tank.
• The supply valve controls the flow rate of hydrogen supplied to the anode of the fuel cell stack.
• The discharge valve is located in the hydrogen discharge line.
• The controller estimates the pressure of hydrogen flowing into the anode of the fuel cell stack and controls the supply and discharge valves based on this pressure estimate.

Potential Applications

This technology can be applied in various fuel cell systems, including automotive, stationary power generation, and portable electronic devices.

Problems Solved

This technology helps optimize the flow of hydrogen into the fuel cell stack, ensuring efficient operation and prolonging the lifespan of the fuel cell system.

Benefits

The system improves the overall performance and efficiency of fuel cell systems, leading to reduced emissions and lower operating costs.

Potential Commercial Applications

This technology can be utilized in the automotive industry for hydrogen fuel cell vehicles, as well as in backup power systems for residential and commercial buildings.

Possible Prior Art

One possible prior art could be the use of pressure sensors and control valves in fuel cell systems to regulate hydrogen flow. However, the specific configuration with an ejector and controller as described in this patent application may be novel.
