Hydrogen production with nickel powder cathode catalysts in microbial electrolysis cells
Although platinum is commonly used as catalyst on the cathode in microbial electrolysis cells (MEC), non-precious metal alternatives are needed to reduce costs. Cathodes were constructed using a nickel powder (0.5–1 mm) and their performance was compared to conventional electrodes containing Pt (0.002 mm) in MECs and electrochemical tests. The MEC performance in terms of coulombic efficiency, c...
متن کاملHigh power density microbial fuel cell with flexible 3D graphene-nickel foam as anode.
The structure and electrical conductivity of anode play a significant role in the power generation of microbial fuel cells (MFCs). In this study, we developed a three-dimensional (3D) reduced graphene oxide-nickel (denoted as rGO-Ni) foam as an anode for MFC through controlled deposition of rGO sheets onto the nickel foam substrate. The loading amount of rGO sheets and electrode surface area ca...
متن کاملHydrogen gas production in a microbial electrolysis cell by electrohydrogenesis
Electrohydrogenesis is a bio-electrochemical process where organic material is microbially oxidized to protons and electrons, which in turn are reduced to form hydrogen gas (H2). The reactor in which these reactions occur is termed a microbial electrolysis cell (MEC). The microorganisms that colonize the anode are known as electricigens and behave as biological catalysts, significantly reducing...
متن کاملA microbial fluidized electrode electrolysis cell (MFEEC) for enhanced hydrogen production
A microbial fluidized electrode electrolysis cell (MFEEC) was used to enhance hydrogen gas production from dissolved organic matter. Flowable granular activated carbon (GAC) particles were used to provide additional surface area for growth of exoelectrogenic bacteria. The use of this exoelectrogenic biofilm on the GAC particles with fluidization produced higher current densities and hydrogen ga...
متن کاملThe significance of key operational variables to the enhancement of hydrogen production in a single-chamber microbial electrolysis cell (MEC)
Microbial electrolysis cell (MEC) is one of the promising and cutting-edge technologies for generating hydrogen from wastewater through biodegradation of organic waste by exoelectrogenic microbes. In the MECs, the operational parameters, such as applied voltage (Eap), anode surface area, anode-cathode distance, and N2/CO2 volume ratio have a significant impact on the hydrogen yield and producti...
