Integration of State of Health Indicators for Proton Exchange Membrane Fuel Cells

Abstract:

In this paper， operating conditions containing more “irreversible degradation” information are filtered based on the method of the information theory. The sequential quadratic programming method is used to integrate operating conditions and the output power into the integrated state of health（SOH） indicator. Compared to the indicator with output power as SOH， the integrated SOH indicator improves by 22.83%， 91.96% ，and 55.60% in the monotonicity， consistency of aging， and comprehensive performance， respectively.
