Fig. 9From: New fragmented electro-active biofilm (FAB) reactor to increase anode surface area and performance of microbial fuel cellOpen circuit voltage (OCV) generated at different anodic pH in MFC and FAB-MFC reactor using rubber, 3D, and K3 MEJ-dish at 27 ℃. Junction refers to the space between the electrode and MEJ-dish (where MEJ-dish was connected to the electrode); K3 (open), 3D (partly opens), and rubber lock (close) the junctionBack to article page
