It is understood that “Photomicrobial fuel cells (PMFCs)” can generate electricity from both photosynthesis and catabolism of endogenous carbohydrates in the light and from catabolism alone in the dark circumstance. In the present study, direct electron transfer from photomicrobial strain, Rhodopseudomonas palustris, to the anodes characterised with polymer-coated electrocatalytic composite were investigated. In addition, the examination of operation stability of a self-constructed photomicrobial fuel cell (PMFC) was also studied.
