FUEL CELL SYSTEM FOR GENERATING ELECTRIC POWER AND METHOD OF CONTROLLING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17875132 titled 'FUEL CELL SYSTEM FOR GENERATING ELECTRIC POWER AND METHOD OF CONTROLLING SAME
Simplified Explanation
The patent application describes a fuel cell system and a method for controlling the system to improve its startability. The system aims to remove hydrogen, air, and generation water from a large-sized fuel cell system after it finishes operation. This is achieved by selecting one fuel cell module as a power supply module to operate an air compressor, ensuring a constant amount of generated electricity necessary to restart the system.
- The fuel cell system improves next-time startability by removing residual gases and liquids after operation.
- An air compressor is operated by a selected fuel cell module to remove hydrogen, air, and generation water.
- This method improves the durability of the fuel cell stack and ensures a constant amount of generated electricity for restarting the system.
Potential Applications
The technology described in this patent application has potential applications in various industries and sectors, including:
- Large-scale fuel cell systems for power generation.
- Automotive fuel cell systems.
- Industrial fuel cell systems for backup power or remote locations.
Problems Solved
The patent application addresses the following problems:
- Residual gases and liquids remaining in a fuel cell system after operation can hinder its startability.
- Accumulation of hydrogen, air, and generation water can affect the durability of the fuel cell stack.
- Inadequate electricity generation during system restart can lead to operational issues.
Benefits
The described technology offers several benefits:
- Improved startability of fuel cell systems by effectively removing residual gases and liquids.
- Enhanced durability of the fuel cell stack, leading to longer system lifespan.
- Ensured constant amount of generated electricity for a smooth restart of the system.
Original Abstract Submitted
A fuel cell system and the method of controlling the fuel cell system improve next-time startability in the following manner. Hydrogen, air, generation water, and the like that remain inside a large-sized fuel cell system needs to be removed after finishing operation of the large-sized fuel cell system, such as a fuel cell system for generating electric power. To the present end, when an air compressor needs to be operated, one fuel cell module is selected as a power supply module, and an air compressor is operated by the power supply module. Thus, durability of a fuel cell stack is improved, and at the same time, a constant amount of generated electricity necessary to restart the large-sized fuel cell system is ensured.
