FUEL CELL STACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18587495 titled 'FUEL CELL STACK
Simplified Explanation: The patent application describes a fuel cell stack with a unique design for efficient gas flow and water drainage.
- The cell stack body is formed by stacking power generation cells in a specific direction.
- An exhaust gas flow path allows the discharge of reaction gas from the power generation cells.
- A flow path forming portion facilitates water drainage from the upstream to the downstream side of the gas flow path.
- The flow path forming portion includes a communicating tube with openings to allow water flow and a diaphragm portion at the inlet of the drainage flow path.
Key Features and Innovation:
- Efficient gas flow and water drainage system in a fuel cell stack.
- Unique design for stacking power generation cells for optimal performance.
- Integration of a communicating tube and diaphragm portion for effective water drainage.
Potential Applications: This technology can be applied in various fuel cell systems for improved efficiency and performance.
Problems Solved: This technology addresses issues related to gas flow and water drainage in fuel cell stacks, ensuring optimal operation.
Benefits:
- Enhanced efficiency in gas flow and water drainage.
- Improved performance and longevity of fuel cell systems.
Commercial Applications: Potential commercial applications include automotive fuel cells, stationary power generation systems, and portable fuel cell devices.

Original Abstract Submitted
A fuel cell stack including a cell stacked body formed by stacking power generation cells in a predetermined direction, an exhaust gas flow path penetrating the cell stacked body in the predetermined direction so as to discharge a reaction gas supplied to the plurality of power generation cells, and a flow path forming portion forming a drainage flow path so that water flows from an upstream side to a downstream side of the exhaust gas flow path. The flow path forming portion includes a communicating tube disposed in the exhaust gas flow path so as to communicate with the upstream side and the downstream side of the exhaust gas flow path respectively through a first opening and a second opening of the communicating tube, and the flow path forming portion further includes a diaphragm portion at an inlet of the drainage flow path.
