Abstract

The invention provides a fuel cell life prediction method and device and a computer readable storage medium. The fuel cell life prediction method includes the steps that classification is carried outaccording to operation condition data of a fuel cell, key parameters in a fuel cell voltage recession model are obtained through data fitting, the fuel cell voltage recession model is constructed, andthe voltage recession condition of a fuel cell is estimated and predicted according to the fuel cell voltage recession model; meanwhile, the key parameters of the fuel cell voltage recession model are corrected periodically so that the accuracy of fuel cell life estimation can be ensured so as to guarantee the accuracy of estimation results.

Description

technical field [0001] The present application relates to the field of fuel cells, in particular to a fuel cell life prediction method, a prediction device and a computer-readable storage medium. Background technique [0002] Due to its high efficiency, cleanliness, and pollution-free advantages, fuel cells have attracted extensive attention and have broad development prospects. One of the technical bottlenecks of proton exchange membrane fuel cells for vehicles at present is their service life. In order to prolong the service life of the fuel cell stack, it is necessary to be able to accurately estimate and predict its service life, which is also a very important aspect in the current research. [0003] The service life of the fuel cell is measured by the output performance. The internal structure of the fuel cell changes with use, which will affect its performance decay rate to a certain extent, especially in the middle and late stages of the fuel cell life. Therefore, t...
