Bristol BioEnergy Centre

The Microbial Fuel Cell (MFC)is a technology that can directly convert organic waste into electricity. The Bioenergy and Self Sustainable Systems Theme is all about bringing this technology to the real world and making the utilisation of waste into energy a reality. Furthermore, being able to generate electricity from naturally occurring biomass, gives robots a novel degree of autonomy that allows their prolonged operation in environments that are inaccessible or even lethal to human beings.

Breaking News

The team has recently demonstrated for the first time the charging of a commercially available mobile phone, using Microbial Fuel Cells (MFCs) fed with real neat urine. The membrane-less MFCs were made out of ceramic material and employed plain carbon based electrodes. View the relevant scientific publication.
