FUEL CELL SYSTEM AND CONTROL METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240297315 titled 'FUEL CELL SYSTEM AND CONTROL METHOD THEREOF
The abstract describes a fuel cell system that includes a fuel cell stack with a cathode and an anode, an air compressor sending air to the cathode, an air adjustment valve regulating air flow, a hydrogen flow line delivering hydrogen to the anode, and a controller adjusting compressor speed or valve opening based on battery voltage or hydrogen concentration.
- Fuel cell system with cathode, anode, air compressor, air adjustment valve, hydrogen flow line, and controller
- Air compressor sends air to cathode, while air adjustment valve regulates air flow
- Hydrogen flow line delivers hydrogen to anode and discharges it after passing through
- Controller adjusts compressor speed or valve opening based on battery voltage or hydrogen concentration
- Stop control mode of the fuel cell stack is activated based on these adjustments
