N2 - The aim of this work is to determine the optimum operating conditions for the process of preparing anode electrocatalysts for direct sodium borohydride fuel cell (DSBHFC). Pt-Au/C electrocatalysts were studied as the anode catalysts while Pt/C were chosen as a cathode catalyst. Anode electrocatalysts were produced by the precipitation method. In this work, pH, temperature, drying time and Pt/Au ratio were selected as independent process parameters and their effects on dependent parameters, such as power density and hydrogen production rate, were investigated using response surface methodology (RSM). Based on this methodology, it was found that the maximum power density and the minimum hydrogen production rate were 354.4mWcm-2 and 30mlmin-1 respectively. These findings were obtained at 90°C, 9.27 pH, 61.07h of drying time, and 93.54% Au ratio to total metal ratio.
