Description
Hao Wang and co-authors present a 2024 pore scale study of squeezing the gas layer in a hydrogen fuel cell. Ships face tight emission rules, which lifts interest in these cells at sea. When the cell is bolted shut, ribs press the gas diffusion layer and warp its pores, and that warp shapes how gas and current flow.
A 3D lattice model joins gas flow with the cell's chemistry at pore scale. Squeezing deepened the oxygen dip along the flow path and cut the lowest current density. Higher pore share near the catalyst helped oxygen in and water vapor out, which lifted mean current. The team ranks which knobs, from voltage gap to pore gradient, sway output most.
