II. Microbial Fuel Cells

Microbial fuel cells are electronic devices that utilize exoelectrongenic bacteria (e.g., Shewanella oneidensis and E. coli.) to recover chemical energy from wastewater.

1. Solar-Assisted Microbial Fuel Cells

Solar-assisted microbial fuel cell enables continuous, self-sustained hydrogen gas generation based solely on sunlight and wastewater.

2. 3D Electrodes for Microbial Fuel Cells

The structure and electrical conductivity of bioanode play a significant role in the power generation of microbial fuel cells. We aim to develop 3D porous and conductive electrode structures for improving the electron collection efficiency at the bacteria/electrode interface.
