摘要：Proton exchange membrane(PEM)fuel cell has been regarded as a promising approach to the decarbonization and diversification of energy *** recent years,durability and cost issues of PEM fuel cells are increasingly significant with the rapid increase of power ***,the failure to maintain the cell consistency,as one major cause of the above issue,has attracted little ***,this study intends to figure out the underlying cause of cell inconsistency and provide solutions to it from the perspective of multi-physics transport coupled with electrochemical *** PEM fuel cells with electrodes under two compression modes are firstly discussed to fully explain the relationship of cell performance and consistency to electrode structure and multi-physics *** result indicates that one main cause of cell inconsistency is the intrinsic conflict between the separated transport and cooperated consumption of oxygen and electron throughout the active ***,a mixed-pathway electrode design is proposed to reduce the cell inconsistency by enhancing the mixed transport of oxygen and electron in the *** is found that the mixing of pathways in electrodes at under-rib region is more effective than that at the under-channel region,and can achieve an up to 40%reduction of the cell inconsistency with little(3.3%)sacrificed *** addition,all the investigations are implemented based on a self-developed digitalization platform that reconstructs the complex physical–chemical system of PEM fuel *** fully observable physical information of the digitalized cells provides strong support to the related analysis.
