LeDuc & Gregory Create World's Smallest Fuel Cell Fueled by Bacteria

Mechanical Engineering Professor Philip R. LeDuc and Civil & Environmental Engineering Assistant Professor Kelvin B. Gregory have created the world's smallest fuel cell powered by bacteria. The new device, the size of a single strand of human hair, generates energy from the metabolism of bacteria on thin gold plates in micro-manufactured channels. The fuel cell recruits necessary bacteria to create a biofilm that utilizes natural organic compounds as fuel to generate power.

Both researchers report that the evolution of microbial electricity generation is motivated by the potential for renewable energy sources and waste biomass to serve as a fuel for large-scale electricity generation.  Excerpted from the full Press Release.
