FUEL CELL SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17967593 titled 'FUEL CELL SYSTEM
Simplified Explanation
The patent application describes a fuel cell system that includes a radiator, coolant supply pump, COD heater, valve, and controller. The system is designed to control the flow of coolant and consume energy generated by the fuel cell stack based on the state of charge (SOC) of a battery and the operating state of the fuel cell stack.
- The fuel cell system includes a radiator that exchanges heat with coolant discharged from the fuel cell stack.
- A coolant supply pump is used to supply coolant to the fuel cell stack.
- A COD heater consumes electric power generated by the fuel cell stack.
- A valve is connected to the fuel cell stack, radiator, coolant supply pump, and COD heater to control the flow of coolant.
- The controller is responsible for controlling the operating start time and output of the COD heater based on the SOC of a battery and the operating state of the fuel cell stack.
- The controller also controls the valve to ensure that the coolant flows to the COD heater in a temperature control section after the cold start section of the fuel cell stack.
Potential Applications
- Automotive industry - This fuel cell system can be used in electric vehicles to efficiently manage the energy generated by the fuel cell stack and control the temperature of the coolant.
- Power generation - The system can be applied in stationary fuel cell power plants to optimize energy consumption and maintain proper cooling of the fuel cell stack.
Problems Solved
- Efficient energy consumption - The system intelligently controls the COD heater to consume energy generated by the fuel cell stack based on the SOC of a battery and the operating state of the fuel cell stack, ensuring efficient energy usage.
- Temperature control - By directing the coolant flow to the COD heater in a temperature control section, the system effectively manages the cooling of the fuel cell stack, preventing overheating and maintaining optimal performance.
Benefits
- Improved energy efficiency - The system optimizes the consumption of energy generated by the fuel cell stack, leading to improved overall energy efficiency.
- Enhanced performance and reliability - By controlling the temperature of the fuel cell stack, the system ensures optimal performance and reliability of the fuel cell system.
- Extended battery life - The intelligent control of the COD heater based on the SOC of a battery helps in preserving the battery life by efficiently utilizing the energy generated by the fuel cell stack.
Original Abstract Submitted
Described herein is a fuel cell system that includes a radiator configured to exchange heat with coolant discharged from a fuel cell stack, a coolant supply pump configured to supply the coolant to the fuel cell stack, a COD heater configured to consume electric power generated by the fuel cell stack, a valve connected to the fuel cell stack, the radiator, the coolant supply pump, and the COD heater to control a flow of the coolant, and a controller configured to control an operating start time and output of the COD heater to consume energy generated by the fuel cell stack depending on a state of charge (SOC) of a battery and an operating state of the fuel cell stack. The controller controls the valve so that the coolant flows to the COD heater in a temperature control section after a cold start section of the fuel cell stack.
