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

This abstract first appeared for US patent application 17880078 titled 'FUEL CELL SYSTEM AND METHOD FOR CONTROLLING THE SAME

Simplified Explanation

The disclosed patent application is about a fuel cell system and a method for controlling it. The system operates in a constant current mode, where the output current of the fuel cell stack remains constant. The purpose of the invention is to prevent the fuel cell stack from flooding in this mode by controlling different units of the system based on the target output current.

  • The patent application describes a fuel cell system and a method for controlling it.
  • The system operates in a constant current mode, where the output current of the fuel cell stack remains constant.
  • The invention aims to prevent the fuel cell stack from flooding in this mode.
  • The control method varies depending on the size of the target output current.
  • The hydrogen supply unit, air supply unit, or hydrogen recirculation unit are controlled differently based on the target output current.
  • The goal is to avoid local flooding of the fuel cell stack during constant current operation.

Potential Applications

The technology described in this patent application has potential applications in various industries and sectors, including:

  • Automotive industry: The fuel cell system can be used in hydrogen-powered vehicles, providing a more efficient and reliable power source.
  • Renewable energy: The system can be utilized in renewable energy systems, such as stationary fuel cell power plants, to generate electricity from hydrogen.
  • Portable power: The technology can be applied in portable fuel cell systems, providing a compact and clean energy source for various applications, such as camping or emergency power supply.

Problems Solved

The patent application addresses the following problems:

  • Local flooding of the fuel cell stack during constant current operation mode.
  • Inefficient control of the hydrogen supply unit, air supply unit, or hydrogen recirculation unit.
  • Lack of a method to prevent flooding based on the target output current.
  • Potential damage to the fuel cell stack due to flooding.

Benefits

The technology described in the patent application offers several benefits:

  • Improved efficiency and performance of the fuel cell system during constant current operation mode.
  • Prevention of local flooding in the fuel cell stack, reducing the risk of damage and improving system reliability.
  • Optimal control of the hydrogen supply unit, air supply unit, or hydrogen recirculation unit based on the target output current.
  • Enhanced safety and longevity of the fuel cell system.
  • Potential for wider adoption of fuel cell technology in various industries and applications.


Original Abstract Submitted

Disclosed is a fuel cell system and a method for controlling the same which in a constant current operation mode in which an output current of a fuel cell stack is constant, controls a hydrogen supply unit, an air supply unit, or a hydrogen recirculation unit differently depending on the size of a target output current to prevent the local flooding of the fuel cell stack in the constant current operation mode.
