FUEL CELL SYSTEM AND CONTROL METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18135419 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 the fuel cell stack even after the fuel cell has stopped operating. The system includes a pressure sensor, an air cutoff valve, and a controller to manage the pressurization 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 stack inlet
- 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 post-operation - Prevents air leakage and potential damage to the fuel cell stack
- Benefits
- Extends the lifespan of the fuel cell stack - Improves overall efficiency of the fuel cell system
- Potential Commercial Applications
- Optimizing Fuel Cell Systems for Longevity and Efficiency
- Potential Commercial Applications
---
- Possible Prior Art
There may be prior art related to controlling air flow in fuel cell systems to maintain pressure and airtightness, but specific examples would need to be researched further.

- Unanswered Questions
- How does the system handle variations in air pressure during operation?
The abstract does not provide details on how the system adjusts to fluctuations in air pressure within the cathode side.
- What is the impact of the control method on overall fuel cell system performance?
The abstract does not mention the potential effects of the control method on the efficiency or output of the fuel cell system.
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.
