Abstract For the high-speed reaction in a fuel cell,some data are immeasurable when the cell is in function.In order to get a better understanding of the complex internal flow structure,the transmission of chemical composition,optimize water and thermal management,and to shorten the design and optimization cycle for a fuel cell,a mathematic model and numerical simulation are needed.Based on COMSOL Multiphysics 3.3a,a two-dimension cell model was built and numerical simulation was conducted on the electric current density,gas velocity,gas pressure and moisture of a fuel cell.In the simulation process,the maximum electric current density is(9 027 A/m~2) and the maximum flow velocity is 0.7 m/s.
