Description
Yuvraj Maphrio Mao and four co-authors boost a miniature microbial fuel cell's output more than sevenfold by dusting its anode with graphene quantum dots. These tiny fuel cells, which harvest electricity from wastewater microbes, could power sensors and implants but remain too weak. The bottleneck is electron transfer at the electrode.
Electrodes were screen-printed on glass, a durable and fouling-resistant format, then the anode was drop-coated with quantum dots to enlarge its active surface. Fed reverse-osmosis wastewater, the modified cell produced about three hundred thirty-two nanowatts per square centimeter against forty-five for the bare electrode. Output held up over long operation. The authors present glass screen printing plus quantum dots as a practical manufacturing route.
