Abstract: | The paper reports the operation of a new-design microbial fuel cell using compost leachate as a substrate, oxygen/electrodeposited MnOx cathode and a new-anode concept with graphite modified by an iron/sulfur solid chemical catalyst which almost eliminates the starting delay time and gives very high current and power densities, I ~ 25 A m− 3 at Pmax ~ 12 W m− 3 or I ~ 3.8 A m− 2 at Pmax ~ 1.8 W m− 2. |
