Microbial fuel cell technology is an emerging technology with the potential to support renewable energy production and promote sustainable development. However, high cost of materials has militated against large scale implementation of this technology, especially when considering the high cost of Nafion used as proton exchange membrane. The successful application of Plaster of Paris slurry(gypsum) as proton exchange membrane as highlighted in this work, suggests the possibility of reduced cost in the development of this technology. Also, the architectural design described in this work makes...
