A development of membraneless percarbonate/hydrazine fuel cell

This paper describes the continuous flow operation of membraneless sodium percarbonate fuel cell using acid/alkaline bipolar electrolyte. here,hydrazine is used as a fuel and sodium percarbonate is used as an oxidant under alkaline-acid media configuration. sodium percarbonate affords hydrogen peroxide in aqueous medium. in our operation,the laminar flow based microfluidic membranleless fuel cell achieved a maximum power density of 24.5 mw cm-2 when using alkaline hydrazine as the anolyte and acidic percarbonate as the catholyte at room temperature with a fuel mixture flow rate of 0.3 ml min-1. 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.
