Effect of permeability on the dynamic field in the PEM fuel cell

A two dimensional PEM fuel cell model is developed, which considers transient of mass, heat and momentum transfer in the gas channels and diffusers at both the anode and cathode sides of the PEM fuel cell.

Description
Summary:A two dimensional PEM fuel cell model is developed, which considers transient of mass, heat and momentum transfer in the gas channels and diffusers at both the anode and cathode sides of the PEM fuel cell. This modelling visualizes the effect of permeability on the dynamic behaviour of the velocity and pressure profiles in the parallel flow field in the transient model of PEMFC fuel cell. The 2D numerical simulations were obtained using the finite volume method. The results demonstrate the difference between the flow in a continuous medium and a porous medium. •A two dimensional transient model of PEM fuel cell is developed.•The effect of permeability explains the flow in a continuous and a porous medium.•The field of velocity and pressure are presented in the parallel flow field.•The two velocity components (x) and (y) is considered.•We show the relation between the velocity and the pressure in this type of flow.
