getting back to basics with the microbial fuel cell

researchers at penn state announced significant progress in the development of a wastewater-to-electricity microbial fuel cell by skipping the expensive bits (polymeric proton-exchange membranes) in favor of cheap stuff (carbon paper).

sometimes it’s good to think simple – this team got a more than 5-fold increase in output by replacing the high-tech polymeric proton exchange membrane with carbon paper. so sometimes “good enough” is “even better.”
