Multi-parameter optimization of stepwise distribution of parameters of gas diffusion layer and catalyst layer for PEMFC peak power density

•A 3D, two-phase flow, non-isothermal agglomerate model is established.•Multi-parameter optimization of stepwise distribution of four parameters are conducted.•In X, Y and Z direction, maximal peak power density occurs when optimization voltage is 0.4 V.•The parameters obtained at 0.4 V along Z-Axis...
