Supercapacitor　activated　carbon　(SC-AC)　is　a　novel　activated　carbon　material　that　has　super　large　specific　surface　area,　mesopore-rich　structure　and　high　capacitance.　In　this　text,　this　supercapacitor　material　was　used　to　modify　carbon　cloth　anode　to　enhance　the　performance　of　urine-powered　microbial　fuel　cell　(UMFC).　The　measurements　showed　that　both　the　specific　surface　area　and　the　electrical　conductivity　were　increased　significantly　after　modification.　The　synergistic　reaction　of　high　specific　surface　area　and　high　capacitance　made　the　number　of　microbes　attached　to　carbon　cloth　modified　with　SC-AC　(SC-AC/CC)　was　far　larger　that　of　the　blank　carbon　cloth　(CC).　The　maximum　power　densities　of　the　UMFC　assembled　SC-AC/CC　anode　was　555.10　mW•m-2　which　was　1.8　times　higher　than　that　of　the　blank　anode.　These　findings　demonstrate　that　these　novel　super　capacitor　materials　modified　anode　can　be　used　in　UMFCs,　and　effectively　improve　their　performance.　©　2018,　Science　Press.　All　right　reserved.
