MULTI-MODULE FUEL CELL POWER GENERATING SYSTEM AND METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17969467 titled 'MULTI-MODULE FUEL CELL POWER GENERATING SYSTEM AND METHOD THEREOF
Simplified Explanation
The present disclosure describes a method for startup and cold shutdown of a multi-module fuel cell power generating system.
- A first fuel cell module supplies electric power for the startup and cold shutdown of a second fuel cell module.
- The second fuel cell module uses the electric power from the first module to perform its own startup or cold shutdown.
- This approach reduces the number of high-voltage batteries, low-voltage batteries, and bi-directional low voltage DC-DC converters (BLDCs) needed for multi-module fuel cell power generation.
- It also reduces control complexity.
Potential Applications
- Multi-module fuel cell power generating systems
- Start-up and cold shutdown processes in fuel cell systems
Problems Solved
- Reduction in the number of batteries and converters needed for multi-module fuel cell power generation
- Simplification of control complexity
Benefits
- Cost savings due to reduced number of components
- Simplified control system
- Improved efficiency in startup and cold shutdown processes
Original Abstract Submitted
The present disclosure relates to startup and cold shutdown (CSD) of a multi-module fuel cell power generating system. According to the present disclosure, a first fuel cell module may supply electric power that is required for startup and cold shutdown of a second fuel cell module, and the second fuel cell module may perform the startup or cold shutdown of the second fuel cell module by using the electric power supplied from the first fuel cell module. According to the present disclosure, the numbers of high-voltage batteries, low-voltage batteries and bi-directional low voltage DC-DC converters (BLDCs) used for multi-module fuel cell power generation may be reduced and control complexity may be reduced.
