Abstract

The invention discloses a fuel cell health prediction method and system, and belongs to the technical field of fuel cells. The method comprises the steps: obtaining the aging data of a fuel cell, including source domain data and target domain data; extracting consistent health feature data from the source domain data and the target domain data, namely source domain health feature data and target domain health feature data; pre-training a basic model by using the source domain health feature data, and determining parameters of the basic model; migrating parameters of the basic model to a fuel cell degradation model, and training the fuel cell degradation model by using the target domain health feature data to obtain a migration model; performing health prediction on the target domain fuel cell by using the migration model and the target domain data; and smoothing the health prediction result of the fuel cell by adopting a particle filtering algorithm to realize probabilistic prediction of the residual life of the fuel cell. The source domain knowledge is applied to the target domain, and the health state of the fuel cell can be accurately predicted only by using a small amount of data of the target domain.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell health prediction method and system. Background technique [0002] Energy and ecology are two major themes in today's society. In order to achieve "carbon neutrality", energy transformation has become a major strategic direction. Fuel cells convert chemical energy directly into electrical energy by means of electrochemical reactions, and have the characteristics of high conversion efficiency and environmental protection. At present, domestic fuel cells have not yet been commercialized on a large scale, and are still in their infancy, and their durability has become a bottleneck restricting the large-scale application of fuel cells. Therefore, it is necessary to carry out research on effective health assessment and control of fuel cells to achieve safe and efficient operation of fuel cells. Health prediction of fuel cells is an important part of their health assess...
