Fig. 5From: New fragmented electro-active biofilm (FAB) reactor to increase anode surface area and performance of microbial fuel cellDifferent microbial electrode jacket-dish (MEJ-dish) used during this study a 3D, b 3D design, c Rubber, d K3 MEJ-dish, and e–g junction between the electrode and MEJ-dish: partly opened (closed), open, and locked (closed). Locked (closed) indicates no space between the electrode and MEJ-dish, partly open shows the upper part is open, but the lower part is partially open or closed, and open means the connection part is exposed for microbial attachmentBack to article page
