The reaction selectivity of Pt loading carbon electrocatalysts (Pt/C) having different Pt particle sizes was electrochemically evaluated in the presence of methanol and O2. The electrochemical measurement of these electrocatalysts was performed using a porous microelectrode technique without any binder resin. In this study, we found an electrocatalyst which exhibits a reaction selectivity during the competitive reactions of methanol oxidation and O2 reduction. For the Pt/C of O2 reduction, the desired electrocatalyst is required to retain a low Pt loading amount irrespective of Pt particle size. For the methanol oxidation, the electrocatalyst having a Pt particle size around 4 nm is effective.
