Fault diagnosis techniques play a crucial role in the normal operation of proton exchange membrane fuel cells. In this paper
we propose a diagnostic technique based on equivalent circuit and KOA-CNN framework
which obtains the PEMFC impedance spectrum information by using electrochemical impedance spectroscopy (EIS) and uses the equivalent circuit for parameter identification
and uses the fitted circuit parameters as the training data for the diagnostic algorithm
and extracts the fault features by using a convolutional neural network
which can significantly improve the accuracy of PEMFC fault diagnosis. The Kepler optimization algorithm convergence speed
strong global search ability
and few parameters to optimize the hyperparameters of the convolutional neural network
to get an optimal convolutional neural network parameters
which can significantly improve the accuracy of fuel cell fault diagnosis. It is verified that the accuracy of this method reaches 99.75% in the fault diagnosis of water flooding
membrane drying and oxygen starvation.
