We present a microfabricated paper-based microbial fuel cell (MFC) generating a maximum power of 5.5 μW/cm(2). 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 1.9 × when two MFC devices were stacked in series, while operating lifetime was significantly enhanced in parallel.
我们展示了一种基于纸张的微生物燃料电池（MFC），其最大功率为 5.5 μW/cm(2)。该 MFC 的特点包括：（1）通过渗透磺化的聚苯乙烯磺酸钠来制备纸张质子交换膜；（2）通过图案化光致抗蚀剂的疏水屏障来制造微结构的纸张腔室。一旦向 MFC 中加入接种物和阴极电解液，就会立即产生 74 μA 的电流。这种基于纸张的 MFC 具有使用方便、生产成本低和便携性高等优点。当两个 MFC 设备串联时，产生的电压增加了 1.9×，而在并联时，其工作寿命则显著延长。
