In this investigation, a 3-D modeling of a PEM (polymer electrolyte membrane) fuel cell has been presented by considering Carbon nanotube (CNT) as the electrode and Cobalt as catalyst. Conventional fuel cells utilize graphite electrodes and platinum catalyst. Compared to mechanical and electrical properties of graphite, CNTs offer good mechanical strength and high current density. Similarly Cobalt has been considered as a cost effective counterpart to platinum. The simulation was carried out at
