Abstract

• Living Plant Microbial Fuel Cell (P-MFC) is the kind of bio volt-photo galvanic cell which converts solar energy into green electricity. The plant synthesized Rhizo-deposit, mostly in the form of carbohydrate, at the sphere of the root through the photo-synthesis process. The microbes of the Rhizo sphere decompose the Rhizo-deposit and converts into electric energy via the Microbial Fuel Cell. The carbon blocks were used as the electrode of the microbial fuel cell. Hsin ngou Grass (Eleusine indica) was used to examine the performance of the plant microbial fuel cell and achieved the maximum electric power is 13.86mWm-2 , open circuit voltage is 0.35V and short circuit current density is 162.5mAm-2 as prepared cell. The open circuit voltage is fluctuated with the life time of the microbial fuel cell and the maximum open circuit voltage, 0.8V was observed at the 10th day of the fabrication of the microbial fuel cell.
