9,10-anthraquinone-2,6-disulfonic acid disodium salt/ epoxy graphite composite for anode in microbial fuel cell
Mimi Hani Abu Bakar1, Pasco Neil, F2, Gooneratne, Ravi3, Kim Byung Hong4.
Properties such as electrical conductivity, low resistivity, chemicals and corrosion
resistance are mostly found in carbon based materials. Epoxy resin is excellent for
electrical insulation and can be used as a conductor with the addition of
conductive filler. Combinations of carbon and epoxy show qualities of a
conductive electrode, mechanically strong with design flexibility and thus makes
them suitable as electrodes in microbial fuel cell (MFC). In this study, graphiteepoxy
composites were fabricated with multi-walled carbon nanotube (MWCNT)
embedded in the matrix surface. 9,10-Anthraquinone-2,6-disulfonic acid
disodium salt/polypyrrole (PPy/AQDS) was used as mediator, covalently
electrografted on electrode’s surface. Electrochemical stability of anodes during
continuous operation were measured in air-cathode MFCs. It appears that
maximum power in MFC could be increased up to 42% with surface modification
using PPy/AQDS. Internal resistance (Rint) could be reduced up to 66% with the
inclusion of MWCNT. These findings show that a one-day fabrication of a-readyto-use
conductive electrode is possible for graphite content between 70-80%
(w/w).
