چکیده
The hybrid sulfur (HyS) cycle offers an alternative route to hydrogen and sulfuric acid production using the SO2-depolarized electrolysis (SDE) cell. This work reports most efficient SDE operation date at high concentrations (∼60 wt%) achieved through optimization of operating conditions cell components. We observed that open porosity in porous transport media (PTM) plays a significant role performance as it enables removal from catalyst layer. combination membrane electrode assembly (MEA) components, such Sulfonated Diels Alder Poly (phenylene) (SDAPP) membranes electrodes prepared SGL 29BC PTM, (103.4 kPagauge 125 °C) yielded potentials <700 mV 500 mA/cm2 >60 wt%.

A 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 کاملHigh hydrogen production rate of microbial electrolysis cell (MEC) with reduced electrode spacing.
Practical applications of microbial electrolysis cells (MECs) require high hydrogen production rates and a compact reactor. These goals can be achieved by reducing electrode spacing but high surface area anodes are needed. The brush anode MEC with electrode spacing of 2 cm had a higher hydrogen production rate and energy efficiency than an MEC with a flat cathode and a 1-cm electrode spacing. T...

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...
