This paper presents the continuous flow operation of membraneless sodium percarbonate fuel cell using acid/alkaline bipolar electrolyte. In this membraneless fuel cell, methanol is used as a fuel and sodium percarbonate is used as an oxidant for the first time under "multi-media" configuration. Sodium percarbonate affords hydrogen peroxide in aqueous medium. At room temperature, the laminar flow based microfluidic membraneless fuel cell can reach a maximum power density of 22.25 mW cm(-2) with a fuel mixture flow rate of 0.3 mL min(-1). The developed fuel cell features no proton exchange membrane. The simple planar structured membraneless sodium percarbonate fuel cell enables high design flexibility and easy integration of the microscale fuel cell into actual microfluidic systems and portable power applications.
