FUEL CELL SYSTEM AND CONTROL METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240136549 titled 'FUEL CELL SYSTEM AND CONTROL METHOD THEREOF
Simplified Explanation
The patent application describes a fuel cell system and a control method that ensure the airtightness of the cathode side of a fuel cell stack even after the fuel cell has stopped operating. This is achieved through the use of a stack pressure sensor, an air cutoff valve, and a controller that work together to regulate the pressure of air inside the cathode.
- Air supply line delivers air to the fuel cell stack
- Air discharge line releases post-reaction air
- Stack pressure sensor measures air pressure at the inlet side of the stack
- Air cutoff valve with a bypass line for controlling air flow
- Controller determines pressurization time and torque for the air cutoff valve
---
- Potential Applications
- Automotive industry for fuel cell vehicles - Power generation for stationary applications
- Problems Solved
- Ensures airtightness of the cathode side of the fuel cell stack - Prevents air leakage after fuel cell operation stops
- Benefits
- Improves overall efficiency of the fuel cell system - Extends the lifespan of the fuel cell stack
- Potential Commercial Applications
- Optimizing Fuel Cell Systems for Longevity and Efficiency
- Potential Commercial Applications

Original Abstract Submitted
a fuel cell system and a control method thereof include an air supply line supplying air to a fuel cell stack and an air discharge line discharging post-reaction air, a stack pressure sensor provided in the air supply line to measure pressure of air at an inlet side of the stack supplied to a cathode side of the fuel cell stack, an air cutoff valve provided with a bypass line connecting the air supply line and the air discharge line in the air cutoff valve, and a controller electrically connected to the stack pressure sensor and the air cutoff valve and configured to determine pressurization time and pressurization torque for the air cutoff valve when the controller concludes that it is necessary to shut off air inside a cathode and control the stack pressure sensor and the air cutoff valve according to the determined pressurization time and the determined pressurization torque so that inside of the cathode is airtight even after stopping of a fuel cell in the fuel cell stack is completed.
