AI Technical Summary
Existing open-loop control systems cannot effectively verify the hydration state of fuel cells, leading to performance degradation and shortened lifespan. Furthermore, the rapid electrochemical impedance spectroscopy method is computationally intensive and difficult to apply in industrial applications.
By measuring the current and voltage of the fuel cell, the electrochemical impedance (ECI) is determined, and a closed-loop control system is used to adjust the cathode current to maintain the target ECI, thereby achieving dynamic management of the fuel cell hydration state.
Effective management of fuel cell hydration status improves performance stability and lifespan, reduces the risk of performance degradation, and enhances the system's transient response capability.
