Title:
FUEL CELL PERFORMANCE RECOVERY METHOD
Document Type and Number:
WIPO Patent Application WO/2024/083268
Kind Code:
A1
Abstract:
A fuel cell performance recovery method, comprising: acquiring a high-frequency impedance value, a mass transfer impedance value and a first charge migration impedance value of a target fuel cell; when the high-frequency impedance value and the mass transfer impedance value remain unchanged and the first charge migration impedance value is greater than a reference charge migration impedance value of the target fuel cell in a rated condition, determining that a cathode catalyst of the target fuel cell has been oxidized; when the ratio of the reference charge migration impedance value to the first charge migration impedance value is greater than a target threshold value, controlling the target fuel cell to switch to a first performance recovery condition; and when the ratio of the reference charge migration impedance value to the first charge migration impedance value is less than or equal to the target threshold value, controlling the target fuel cell to switch to a second performance recovery condition.
