A lab-scale proton exchange membrane fuel cells (PEMFCs) is investigated at automotive operating condition. The comparison of the straight-parallel and serpentine PEMFCs is carried out with detailed description of these flow-field configurations. A three-dimensional model was developed taking into account the electrochemical reaction and the evaporation/condensation of water which can influence on the overall flow field. The straight-parallel PEMFC has considerably low internal pressure drop which is beneficial to automotive application. Non-uniform temperature and current density due to flow maldistribution are identified as a challenge to the straight-parallel PEMFC.
