In the present study, a single chamber single electrode microbial fuel cell has been fabricated to generate electricity from the sludge of the sewage treatment plant at two different ambient temperature range of 25 ± 4°C and 32 ± 4°C under aerobic condition. No work has been done yet by using the single electrode in any MFC system; it is hypothesized that single electrode submerged partially in substrate and rest to atmosphere can function as both cathode and anode. The maximum voltage obtained was about 2890 mV after 80 (hrs) at temperature range of 25 ± 4°C, with surface power density of 1108.29 mW/m2. When the ambient temperature was 32 ± 4°C, maximum voltage obtained was 1652 mV after 40 (hrs.) surface power density reduced to 865.57 mW/m2. When amount of substrate was decreased for certain area of electrode at 25 ± 4°C range, electricity generation decreased and it also shortened the time to reach peak voltage. On the other hand, when the ambient temperature was increased to 32 ± 4°C, the maximum potential energy generated was less than that of previous experiment at 25 ± 4°C for the same substrate Also the time to reach peak voltage decreased to 40 hrs. When comparing with other single chamber single electrode MFC, the present model is generating more electricity that any MFC using sewage sludge as substrate except platinum electrode, which is much costlier that electrode used in the present study.

In the present study, novel MFC has been fabricated using the recyclable aluminum can as air-cathode and graphite rod as anode for the treatment of domestic wastewater and simultaneous power generation. Three different substrate (COD) concentrations, high (>800 mg.L-1), medium (250 mg.L-1 - 800 mg.L-1) and low (<250 mg.L-1) were used. The maximum COD removal efficiencies, voltage generation, power densities were found to be 80%, 0.71 V, and 304.46 mW.m-2 respectively in high strength wastewater setup. In both medium and low strength wastewater setups, after 288 hours, the COD was reduced below 50 mg.L-1 thus limiting the electricity generation substantially. Setup with low-strength wastewater produced a maximum CE (%) of 13.80. Overall results showed that although high-strength wastewater produced better and maximum power dens...

a single chamber single electrode microbial fuel cell has been fabricated to generate electricity

± 4°C and 32 ± 4°C under aerobic condition. No work has been done yet by using the single

surface power density of 1108.29 mW/m2
. When the ambient temperature was 32 ± 4°C,
maximum voltage obtained was 1652 mV after 40 (hrs.) surface power density reduced to
865.57 mW/m2
. When amount of substrate was decreased for certain area of electrode at 25 ±
4°C range, electricity generation decreased and it also shortened the time to reach peak voltage.
On the other hand, when the ambient temperature was increased to 32 ± 4°C, the maximum
potential energy generated was less than that of previous experiment at 25 ± 4°C for the same

single chamber single electrode MFC, the present model is generating more electricity that any
MFC using sewage sludge as substrate except platinum electrode, which is much costlier that
electrode used in the present study.
