摘要：

Direct methanol fuel cell (DMFC) is expected as a candidate for portable power supplies because it is able to constitute a miniature fuel cell without a reformer. In this study, a new type of DMFC is reported which is composed of tubular type polymer electrolytes. As the anode catalyst layer, Pt-Ru catalyst-supported carbon fibers were examined by cyclic voltammetry in order to select suitable one. Also, the optimization of Pt-plated electrode was pursued for the cathode catalyst layer. By selecting the carbon fiber and optimizing the Pt-plating, the output power 0.9 mW/cm(2) Of the tubular-type micro DMFC was attained.
