FUEL CELL SYSTEM AND METHOD FOR OPERATING A FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18030550 titled 'FUEL CELL SYSTEM AND METHOD FOR OPERATING A FUEL CELL SYSTEM
Simplified Explanation
The invention is a fuel cell system that includes a fuel cell stack with a cathode, an air compressor integrated in the cathode gas path, and a shut off device. The cathode gas path branches into a main path and a secondary path downstream of the air compressor. The main path can be connected to the inlet of the fuel cell stack, while the secondary path can be connected to the outlet of the fuel cell stack. The shut off device allows for individual or simultaneous shut off of the main and secondary paths.
- The fuel cell system includes a fuel cell stack with a cathode and an air compressor integrated in the cathode gas path.
- The cathode gas path branches into a main path and a secondary path downstream of the air compressor.
- The main path can be connected to the inlet of the fuel cell stack, while the secondary path can be connected to the outlet of the fuel cell stack.
- A shut off device is provided to individually or simultaneously shut off the main and secondary paths.
Potential applications of this technology:
- Automotive industry: The fuel cell system can be used in hydrogen fuel cell vehicles to efficiently generate electricity for propulsion.
- Power generation: The fuel cell system can be utilized in stationary power plants to produce electricity for residential or commercial use.
- Portable devices: The compact and efficient design of the fuel cell system makes it suitable for powering portable electronic devices.
Problems solved by this technology:
- Efficient air supply: The integration of an air compressor in the cathode gas path ensures a consistent and sufficient supply of air to the fuel cell stack.
- Flexibility in operation: The ability to shut off the main and secondary paths individually or together provides flexibility in controlling the flow of cathode gas and optimizing the fuel cell system's performance.
Benefits of this technology:
- Improved efficiency: The integration of an air compressor ensures optimal air supply, leading to improved fuel cell efficiency and overall system performance.
- Enhanced control: The shut off device allows for precise control of the cathode gas flow, enabling better management of the fuel cell system's operation.
- Versatile applications: The compact and flexible design of the fuel cell system makes it suitable for various applications, including automotive, power generation, and portable devices.
