The present method for improving the thermal performance [24] & efficiency of traditional [24] materials and mono-nanomaterials involves adding a variety of nanoparticles to the base material [24]. The purpose of the present study is to carry out a numerical analysis of recent advancements [1] in power density with YSZ [11] (Yttria stabilised zirconia) nanomaterial thin films as anode and cathode materials. From this study it is found that power density for YSZ (Yttria stabilized zirconia) nanomaterial is 1351 ????/???????? at temperature of 600K. From this study, we conclude that for operating temperature range from 600K -800 K, all the Polarization losses like (Activation losses, ohmic losses & concentration losses) which are present at the interface layer between anode and electrolyte decreases. Therefore, the value for Current density & power density increases. YSZ nanomaterial thin film significantly enhances the solid oxide fuel cell efficiency [21]. The author hopes that their study will benefit current researchers and practitioners active [12] in the Sofc [12] in addressing the challenges to increase power density and current density for automotive applications and will also be useful in dealing with solid oxide fuel cell [14] difficulties in a meaningful manner.
