Microbial fuel cells with enhanced bacterial catalytic activity and stability using 3D nanoporous stainless steel anode

The activity and stability of the anode biofilm control the produced power by microbial fuel cells (MFCs). In this study, 3D nanoporous stainless steel (SS) was used as an anode material in MFCs to enhance both the biofilm growth and its adhesion to the support electrode, which would improve the catalytic activity and stability of MFCs anode biofilm. The effect of varying the annealing atmosphere on the SS performance was studied and correlated...
