Microbial Fuel Cell stack performance enhancement through carbon veil anode modification with activated carbon powder.

ABSTRACT: The chemical energy contained in urine can be efficiently extracted into direct electricity by Microbial Fuel Cell stacks to reach usable power levels for practical implementation and a decentralised power source in remote locations. Herein, a novel type of the anode electrode was developed using powdered activated carbon (PAC) applied onto the carbon fibre scaffold in the ceramic MFC stack to achieve superior electrochemical performance during 500 days of operation. The stack equipped with modified anodes (MF-CV) produced up to 37.9 mW (21.1 W m^-3) in comparison to the control (CV) that reached 21.4 mW (11.9 W m^-3) showing 77% increase in power production. The novel combination of highly porous activated carbon particles applied onto the conductive network of carbon
