N2  - Tubular microbial fuel cells (MFC)with air cathode might be amenable to scale-up but with increasing volume a mechanically robust, cost-effective cathode structure is required. Membrane electrode assemblies (MEA)are investigated in a tubular MFC using cost-effective cation (CEM)or anion (AEM)exchange membrane. The MEA fabrication mechanically combines a cathode electrode with the membrane between a perforated cylindrical polypropylene shell and tube. Hydrogel application between membrane and cathode increases cathode potential by ¡«100mV over a 0¨C5.5mA range in a CEM-MEA. Consequently, 6.1Wm.3 based on reactor liquid volume (200 cm3)are generated compared with 5Wm.3 without hydrogel. Cathode potential is also improved in AEM-MEA using hydrogel. Electrochemical Impedance Spectroscopy (EIS)to compare MEA¡¯s performance suggests reduced impedance and enhanced membrane¨Ccathode contact areawhenusing hydrogel. Themaximumcoulombic efficiency observed with CEM-MEA is 71
