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. After the operation of a large-sized fuel cell system, it is necessary to remove hydrogen, air, and generation water from the system. To achieve this, one fuel cell module is selected as a power supply module to operate an air compressor, ensuring the durability of the fuel cell stack and providing a constant amount of generated electricity for restarting the system.
- The fuel cell system improves next-time startability by removing residual hydrogen, air, and generation water after operation.
- An air compressor is operated by selecting one fuel cell module as a power supply module.
- This method ensures the durability of the fuel cell stack and provides a constant amount of generated electricity for restarting the system.
Potential Applications
- Large-sized fuel cell systems for generating electric power.
- Any application where fuel cell systems are used and require improved startability.
Problems Solved
- Residual hydrogen, air, and generation water inside a fuel cell system can hinder its next-time startability.
- Ensuring the durability of the fuel cell stack during the removal process.
- Providing a constant amount of generated electricity necessary for restarting the system.
Benefits
- Improved startability of fuel cell systems.
- Increased durability of the fuel cell stack.
- Consistent and reliable generation of electricity for restarting 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.
