A microbial fuel cell and a method of manufacturing the same areprovided. The microbial fuel cell includes a cathode, an anode, and amicrobial community. The anode is made of an activated carbon preparedfrom waste coffee ground as an electrode material, and the microbialcommunity is adhered to the surface of the activated carbon. Since theactivated carbon prepared from waste coffee ground is beneficial for theadhesion of various microbial communities to form a biofilm, the electrontransfer efficiency of the microbial fuel cell may be improved. |
