| 摘要 |
Methods of improving a performance parameter of a microbial fuel cell are provided according to embodiments of the present invention which include heating an electrode and exposing the heated electrode to ammonia gas to produce a treated electrode characterized by an increased positive surface charge on the electrode surface. Improved performance parameters include increased maximum power density, increased coulombic efficiency, increased volumetric power density and decreased microbial fuel cell operation time to achieve maximum power density
