Can urea be used to generate power using microbial fuel cell (MFC)?
Therefore, it is advantageous to use these waste materials in the form of urea as fuel to generate power using Microbial Fuel Cell (MFC). In this work, we studied the compost soil MFC (CSMFC) unlike typical MFC with urea from the compost as fuel and graphite as a functional electrode.
Are urea fuel cells sustainable?
Urea Fuel cells available in the liquid state are not sustainable and portable 1. However, in soil-based Microbial Fuel Cell (MFC) use natural bacteria or secreted enzymes to break down the fuel, typically to generate electricity from the soil. In MFCs, bacteria and enzymes to act as biocatalysts to produce electricity 1, 2.
Can urea be used as a fuel?
Power generation from urea as fuel is shallow in the liquid state, as shown in various studies done previously 1, 2, 3, 4, 5, 6. However, there is no other technology at present, which can generate electricity from a soil-based MFC, using urea as fuel in compost.
Can urea be used to generate electricity from a soil-based MFC?
However, there is no other technology at present, which can generate electricity from a soil-based MFC, using urea as fuel in compost. The conventional electrodes, like gold, platinum, and palladium-based catalysts, routinely used in the fuel cell industry, are expensive.
Is urea a suitable fuel for MFCs?
Moreover, additional precautions are needed to prevent exposure to gaseous NH 3 due to volatilisation of the liquid fuel. Therefore, the solid-state materials like soil compost are preferred to overcome the risk, as mentioned above for stable behaviour. Among element of urine, urea is a suitable fuel for MFCs.
Can urea be used for energy storage?
However, one of the most exciting uses of urea is in energy storage technology because urea can be considered a hydrogen and ammonia storage material. Previous research has widely documented different energy storage technologies, their classifications, properties, and applications [ 9, 10, 11 ].
