Abstract
We present a microfabricated paper-based microbial fuel cell (MFC) generating a maximum power of 5.5 μW/cm2. The MFC features (1) a paper-based proton exchange membrane by infiltrating sulfonated sodium polystyrene sulfonate and (2) micro-fabricated paper chambers by patterning hydrophobic barriers of photoresist. Once inoculum and catholyte were added to the MFC, a current of 74 μA was generated immediately. This paper-based MFC has the advantages of ease of use, low production cost, and high portability. The voltage produced was increased by 1.9à when two MFC devices were stacked in series, while operating lifetime was significantly enhanced in parallel.
