In order to find a cost-effective,safe and environmentally friendly power supply device,a catalyst-free microfluidic fuel cell(MFC)is constructed using hydrazine hydrate as fuel,graphite as the electrode and cotton thread as the flow path material.The battery performance is tested.The electrochemical performance of MFC with a graphite tube anode and a graphite rod cathode is the best.When the fuel concentration is 0.075 mol/L,the NaOH concentration is 1 mol/L and the electrode distance is 4 mm,the maximum power density of 11.10 μW/cm2 and the current density of 121.45 μA/cm2 are achieved.The proposed MFC has the characteristics of simple material,low cost and convenient assembly,no external pumps are required to maintain the co-laminar flow,showing the potential of integration and miniaturization as portable devices.
