Abstract: 
This presentation will show our recent progress in the development of simulation tools, investigation on transport phenomena, and design for proton exchange membrane fuel cell (PEMFC) at Tianjin University. The simulation tools include 1+1D and 3D models for PEMFC dynamics and design optimization, two-phase direct numerical simulation (DNS) model for droplet dynamics in channel and electrode microstructures, lattice Boltzmann (LB) model with real density and viscosity ratios for two-phase dynamics, and multiphase model for ice formation/growth in electrode microstructures. Some transport phenomena involving gas, liquid and ice, and new structural designs such as metal-foam PEMFC will also be discussed.
