Cross-scale study on water and gas transfer in proton exchange membrane fuel cell considering micro porous layer interfaces

open access: yesEnergy Conversion and Management: X
The maximum power density of a proton exchange membrane fuel cell (PEMFC) is most affected by mass transfer at high current densities, where water flooding hinders oxygen transfer. In this paper, the multiphase and mass transport lattice Boltzmann method
