FUEL CELL STACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18587464 titled 'FUEL CELL STACK
Simplified Explanation: The fuel cell stack described in the patent application includes a body with power generation cells, an exhaust gas flow path for discharging reaction gas, and a communicating tube connecting the upstream and downstream sides of the flow path.
- The fuel cell stack has a unique design with a reduced diameter portion in the exhaust gas flow path, gradually decreasing the flow path area towards the outlet.
- A communicating tube in the flow path connects the small diameter side of the reduced portion to the outlet, improving gas flow efficiency.
Key Features and Innovation:
- Unique design with a reduced diameter portion in the exhaust gas flow path.
- Communicating tube connecting upstream and downstream sides of the flow path.
- Gradual decrease in flow path area towards the outlet for improved efficiency.
Potential Applications: This technology could be applied in various fuel cell systems for power generation, including automotive, residential, and industrial applications.
Problems Solved: This technology addresses issues related to gas flow efficiency and overall performance in fuel cell stacks.
Benefits:
- Improved gas flow efficiency.
- Enhanced overall performance of fuel cell systems.
- Potential for increased energy output.
Commercial Applications: Potential commercial applications include fuel cell vehicles, stationary power generation systems, and portable power sources for various industries.
Prior Art: Further research can be conducted in the field of fuel cell technology to explore similar designs and innovations in exhaust gas flow paths.
Frequently Updated Research: Researchers are continually exploring ways to optimize fuel cell stack designs for improved efficiency and performance.
Questions about Fuel Cell Stack Technology: 1. How does the reduced diameter portion in the exhaust gas flow path contribute to the efficiency of the fuel cell stack? 2. What are the potential environmental benefits of implementing this technology in fuel cell systems?
Original Abstract Submitted
A fuel cell stack including a cell stacked body, an exhaust gas flow path penetrating the cell stacked body in a predetermined direction so as to discharge a reaction gas supplied to a plurality of power generation cells, and a communicating tube disposed in the exhaust gas flow path so as to communicate with an upstream side and a downstream side of the exhaust gas flow path respectively through a first opening and a second opening of the communicating tube. The exhaust gas flow path includes a reduced diameter portion configured to gradually decrease a flow path area toward an outlet of the exhaust gas flow path, and the second opening communicates with the exhaust gas flow paths between an end on a small diameter side of the reduced diameter portion and the outlet of the exhaust gas flow path.
