- The plant microbial fuel cell (P-MFC) is a novel bioelectrochemical device that is commonly used in highly water-saturated ecosystems to produce sustainable energy. However, the use of this system in arid or semi-arid areas has been less well explored to date. This would involve, the use of plants such as prickly pear, which adapts to these adverse conditions and could be an alternative to expand the application of P-MFC. The objective of this research is to use four Opuntia species (succulent plants) for the generation of sustainable electricity via plant-based biobattery design, under open environment and unsaturated water conditions. A Novel vertically integrated plug-in ceramic stick based P-MFCs was constructed, this could reduce the usage of the top-soil surface and aid the possible potential of scale-up design. For a long operating time (30 days), the results showed an average power density of 103.6 mW m …
