In this article, 2D and 3D model of a PEMFC has been simulated in order to study their performance when subjected to similar operating conditions. The comparison reveals interesting phenomena of performance enhancement of the fuel cell. Design of fuel cell channel and stationary studies were done in COMSOL. Variations in current density and electrolyte potential from simulation results were observed when operated at a temperature of 120 degrees C. The electrolyte potential was found to have increased from 1 to 2.5V and the surface pressure due to fluid flow was found to have increased from 3 to 9.58 Pa. (C) 2017 Elsevier B.V.
