. A porous carbon material with its pore size of about
400 nm has been successfully prepared by using silica spheres as
templates and sucrose as carbon precursor, and its performance as
anode of microbial fuel cell was evaluated with E. coli, whose size
(about 200 nm) is a little smaller that the pore of the porous
carbon. The polarization curve measurement demonstrates that
the as-prepared porous carbon provides the microbial fuel cell
with a power output of 1606 mW m2 in the solution containing
2 g/L glucose. To our knowledge, this value is the best among those
that have been reported in literature
