Researchers at Arizona State University have developed a method of fabricating MFCs that can produce high power density. The existing manufacturing processes use bacteria that are not efficient in generating high power density. Also, the existing MEMS MFC design causes high internal resistance resulting in slow start-up and loss of power generation. The method developed by researchers at ASU uses Geobacteraceae enriched bacterial cultures that generate high current and have been shown to increase power densities by as much as 100 times. The MEMS MFCs have been designed such that it decreases the internal resistance which in turn increases the power density and accelerates the start-up time. This also ensures long term sustainability of power generation.
- Electric vehicles
- Consumer electronics
- Wastewater treatment plants (the bacteria could consume the waste material or the organic material and produce supplementary power for the plant)
- Medical applications (Eg. Pacemakers)
- Environment friendly as they use renewable form of energy
- High power density (improved by ~100x)
- Low start-up time
