This study is proposed to investigate the effect of electrode preparation method for Alkaline Fuel Cell using NaOH as an electrolyte on the Fuel Cell performance. The materials used for the preparation of electrode are Pt and Ag on Vulcan XC-72. Surface area of Vulcan XC-72 have different values according to the pretreatment conditions and the dispersion of Pt. is dependent on the impregnation. Particle size of Pt impregnated on unpretreated carbon was observed to be 20-40A and that on pretreated carbon in N? stream at 950℃ was found to be finely dispersed less then 15?. The electrode performance was affected by the particle size of metals and operating temperature. It was revealed from this study that the optimum particle size about 30? and optimum temperature range is between 90-100℃.
