Increased performance of single-chamber microbial fuel cells using an improved cathode structure
Maximum power densities by air-driven microbial fuel cells (MFCs) are considerably influenced by cathode performance. We show here that application of successive polytetrafluoroethylene (PTFE) layersExpand
Power generation in fed-batch microbial fuel cells as a function of ionic strength, temperature, and reactor configuration.
TLDR
It is demonstrated that power densities can be increased to over 1 W/m2 by changing the operating conditions or electrode spacing, which should lead to further improvements in power generation and energy recovery in single-chamber, air-cathode MFCs. Expand
Production of electricity from acetate or butyrate using a single-chamber microbial fuel cell.
TLDR
It is demonstrated that electricity generation is possible from soluble fermentation end products such as acetate and butyrate, but energy recoveries should be increased to improve the overall process performance. Expand
Graphite fiber brush anodes for increased power production in air-cathode microbial fuel cells.
TLDR
Findings show that brush anodes that have high surface areas and a porous structure can produce high power densities, and therefore have qualities that make them ideal for scaling up MFC systems. Expand
Direct biological conversion of electrical current into methane by electromethanogenesis.
TLDR
Results show that electromethanogenesis can be used to convert electrical current produced from renewable energy sources (such as wind, solar, or biomass) into a biofuel (methane) as well as serving as a method for the capture of carbon dioxide. Expand

TLDR
This electrohydrogenic process provides a highly efficient route for producing hydrogen gas from renewable and carbon-neutral biomass resources and is shown to be efficient and sustainable from any type of biodegradable organic matter by electroHydrogenesis. Expand
Electricity generation using membrane and salt bridge microbial fuel cells.
TLDR
The results show that increasing power densities in MFCs will require reducing the internal resistance of the system, and that methods are needed to control the dissolved oxygen flux into the anode chamber in order to increase overall Coulombic efficiency. Expand
Power densities using different cathode catalysts (Pt and CoTMPP) and polymer binders (nafion and PTFE) in single chamber microbial fuel cells.
TLDR
Results demonstrate that cathodes used in MFCs can contain very little Pt, and that the Pt can even be replaced with a non-precious metal catalyst such as a CoTMPP with only slightly reduced performance. Expand
Power generation using different cation, anion, and ultrafiltration membranes in microbial fuel cells.
TLDR
The results show that many types of membranes can be used in two-chambered MFCs, even membranes that transfer negatively charged species. Expand
AMMONIA TREATMENT OF CARBON CLOTH ANODES TO ENHANCE POWER GENERATION OF MICROBIAL FUEL CELLS
Abstract Changes in microbial fuel cell (MFC) architecture, materials, and solution chemistry can be used to increase power generation by microbial fuel cells (MFCs). It is shown here that using aExpand
