Abstract
The aim of this paper was to demonstrate the feasibility of using a Computational Fluid Dynamics tool
for the design of a novel Proton Exchange Membrane Fuel Cell and to investigate the performance of
serpentine micro-channel flow fields. A three-dimensional steady state model consisting of momentum,
heat, species and charge conservation equations in combination with electrochemical equations
has been developed. The design of the PEMFC involved electrolyte membrane, anode and cathode
catalyst layers, anode and cathode gas diffusion layers, two collectors and serpentine micro-channels
of air and fuel. The distributions of mass fraction, temperature, pressure drop and gas flows through
the PEMFC were studied. The current density was predicted in a wide scope of voltage. The current
density – voltage curve and power characteristic of the analysed PEMFC design were obtained.
A validation study showed that the developed model was able to assess the PEMFC performance.
