Numerical optimization of evaporative cooling in artificial gas diffusion layers

•Direct pore-level model allows to describe evaporative cooling in GDL.•Artificial lattice replaces partially saturated GDL with similar morphology.•Kinetic gas theory models pore-level evaporation at water-gas interface.•Evaporation is mostly impacted by GDL porosity, carrier gas type and operating...
