AB - Cell temperature and selection of the reactant gases are crucial parameters  for the design and optimization of fuel cell performance. In this study,  effect of operating conditions on the performance of Solid Oxide Fuel (SOFC)  has been investigated. Application of Response Surface Methodology (RSM) was  applied to optimize operations conditions in SOFC. For this purpose, an  experimental set up for testing of SOFC has been established to investigate  the effect of Hydrogen, Oxygen, Nitrogen flow rates and cell temperature  parameters on cell performance. Hydrogen flow rate, oxygen flow rate,  nitrogen flow rate and cell temperature were the main parameters considered  and they were varied between 0.25 and 1 L/min, 0.5 and 1 L/min, 0 and 1  L/min and 700-800 oC in the analyses respectively. The maximum power density  was found as 0.572 W/cm2 in the experiments.
