APPARATUS AND METHOD FOR CONTROLLING FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17851535 titled 'APPARATUS AND METHOD FOR CONTROLLING FUEL CELL SYSTEM
Simplified Explanation
The patent application describes an apparatus and method for controlling a fuel cell system. The system includes a fuel cell stack, a balance of plant (BOP) for operating the stack, and a fuel cell controller.
- The system includes a first power converter with a bidirectional low voltage DC/DC converter, connected between the fuel cell stack and a first voltage battery.
- There is also a second power converter with a single bidirectional DC/DC converter module, connected between the fuel cell stack and a second voltage battery.
- The controller is configured to operate either the first power converter or the second power converter when the fuel cell system is started or stopped.
- The controller also controls the first power converter or the second power converter to supply driving power to the BOP using electrical energy from the first voltage battery or the second voltage battery.
Potential applications of this technology:
- Fuel cell systems for various applications such as automotive, stationary power generation, and portable power.
- Hybrid power systems that combine fuel cells with other energy sources.
Problems solved by this technology:
- Efficient control of the fuel cell system during startup and shutdown.
- Effective utilization of electrical energy from multiple voltage batteries.
Benefits of this technology:
- Improved overall efficiency of the fuel cell system.
- Enhanced control and management of power flow within the system.
- Increased reliability and performance of the fuel cell system.
