“…Apart from these, the cathode catalyst has the great importance in the bio-electrochemical system such as nickel, nickel-cobalt and nickel-cobalt-phosphorous co-deposition on SS and Cu cathodes have shown the good potential to produce low cost and effective cathodes for MEC. The cathode catalyst and types of microorganism have been used to understand the mechanism of hydrogen production, identify rate limit step, role of crystallinity on hydrogen production reactions as well as to determine their corrosion stability and intrinsic hydrogen production capacity [6]. Various MEC performance parameters must be computed and compared to assess their suitability with respect to published literature for industrial application of MEC.…”

“…MEC technology utilizes bacteria for the catalysis of the electrochemical oxidation or reduction reactions used to produce current [41]. The electrons and protons generated at the anode during oxidation are utilized at the cathode to produce biohydrogen but require additional voltage to trigger biohydrogen production [42]. The optimally applied voltage lies in the range of 0.5-1.0 V [43], which is lower than the voltage required for water electrolysis (1.23-1.8 V) [39], which indicates an advantage to MEC technology.…”

The need for renewable and sustainable fuel and energy storage sources is pressing. Biohydrogen has the potential to be a storable energy carrier, a direct fuel and a diverse building block for various downstream products. Utilizing microbial electrolysis cells (MECs) to produce biohydrogen from residue streams, such as the organic fraction of municipal solid waste (OFMSW), agricultural residues and wastewater facilitate utilization and energy recovery from these streams, paving the path for a circular economy. The advantages of using hydrogen include high gravimetric energy density and, given the MEC pathway, the ability to capture heavy metals, ammonia and phosphates from waste streams, thereby allowing for multiple revenue streams emanating from MECs. A review of the MEC technology and its application was carried out to investigate the use of MEC in sustainable biohydrogen production. This review summarizes different MEC designs of varying scales, including anode materials, cathode materials, and configuration possibilities. This review highlights the accomplishments and challenges of small-scale to large-scale MECs. Suggestions for improving the successful upscaling of MECs are listed, thus emphasizing the areas for continued research.

“…The MEC is governed by a number of input variables or process control indicators, such as temperature, pH, voltage supply, electrode type, electrode configuration, distance between the electrodes, electrical conductivity, and ionic strength [9,10]. These process control indicators are extremely significant in evaluating how the MEC process functions; they provide an indication of process disturbances that might occur so that preventive actions may be implemented as early as possible.…”

A vast quantity of untreated wastewater is discharged into the environment, resulting in contamination of receiving waters. A microbial electrolysis cell (MEC) is a promising bioelectrochemical system (BES) for wastewater treatment and energy production. However, poor design and control of MEC variables may lead to inhibition in the system. This study explored the utilization of Response Surface Methodology (RSM) on the synergistic aspects of MEC and magnetite nanoparticles for wastewater treatment. Influences of temperature (25–35 °C), voltage supply (0.3–1.3 V) and magnetite nanoparticle dosage (0.1–1.0 g) on the biochemical methane potentials (BMPs) were investigated with the aim of optimizing biogas yield, chemical oxygen demand removal and current density. The analysis of variance (ANOVA) technique verified that the quadratic models obtained were substantial, with p-values below 0.05 and high regression coefficients (R2). The optimum biogas yield of 563.02 mL/g VSfed, chemical oxygen demand (COD) removal of 97.52%, and current density of 26.05 mA/m2 were obtained at 32.2 °C, 0.77 V and 0.53 g. The RSM revealed a good comparison between the predicted and actual responses. This study revealed the effective utilization of statistical modeling and optimization to improve the performance of the MEC to achieve a sustainable and eco-friendly situation.
