Various MFCs designs have been developed in the past two decades, including single chamber, double chamber and many
others (Janicek et al., 2014). Among the various MFC configurations, the single chamber air-cathode Cloth Electrode Assembly (CEA) MFC design has a great potential for practical application because of its high performance (Fan et al., 2012). The anode and cathode are separated by a non-woven fabric layer in a CEA-MFC. With this configuration, the distance between anode and cathode is minimized to reduce the internal resistance and increase power production (Fan et al., 2007). Fig. 2 shows the configuration of typical
lab CEA-MFC design.
