FUEL CELL SYSTEM AND METHOD FOR START CONTROL THEREIN - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240039019 titled 'FUEL CELL SYSTEM AND METHOD FOR START CONTROL THEREIN
Simplified Explanation
The abstract describes a fuel cell system that includes a coolant control valve to regulate the flow of coolant through a fluid passage connected to a fuel cell stack. A controller is used to control the opening amount of the coolant control valve during a predefined start sequence when the condition for normal start of the fuel cell stack is met. The coolant control valve is formed by integrating a first valve to switch the flow of coolant into a first pump with a second valve to switch the flow of coolant pumped by the first pump.
- The fuel cell system includes a coolant control valve to regulate coolant flow.
- A controller is used to control the opening amount of the coolant control valve during a start sequence.
- The coolant control valve is formed by integrating a first valve and a second valve.
- The first valve switches the flow of coolant into a first pump.
- The second valve switches the flow of coolant pumped by the first pump.
Potential applications of this technology:
- Fuel cell systems in vehicles
- Power generation systems
- Portable power devices
Problems solved by this technology:
- Efficient regulation of coolant flow in a fuel cell system
- Improved start-up sequence for the fuel cell stack
Benefits of this technology:
- Enhanced performance and efficiency of fuel cell systems
- Improved reliability and durability of the fuel cell stack
- Simplified design and integration of coolant control valve
Original Abstract Submitted
a fuel cell system includes a coolant control valve to switch a flowing path of a coolant passing through a fluid passage connected to a fuel cell stack, and a controller to control a valve opening amount of the coolant control valve while performing a start sequence previously defined, when a condition for normal start of the fuel cell stack is satisfied, and the coolant control valve is formed by integrating a first valve to switch a flowing path of a coolant flowing into a first pump with a second valve to switch a flowing path of a coolant pumped by the first pump.
