“…In contrast, in the study by Gebreslassie et al [146] a maximum H 2 production of 110 mL/g-VS was reported in a similar sDFMEC. This yield was 3.66 times lower than that reported by Nguyen et al Later, in an sDFMFC constructed using a surface-modified stainless steel mesh cathode, a higher H 2 production of 408 mL/g-TS was recorded [147]. The authors modified this system to optimize the electrode performance during the DF process.…”

The over-exploitation of fossil fuels and their negative environmental impacts have attracted the attention of researchers worldwide, and efforts have been made to propose alternatives for the production of sustainable and clean energy. One proposed alternative is the implementation of bioelectrochemical systems (BESs), such as microbial fuel cells (MFCs), which are sustainable and environmentally friendly. MFCs are devices that use bacterial activity to break down organic matter while generating sustainable electricity. Furthermore, MFCs can produce bioelectricity from various substrates, including domestic wastewater (DWW), municipal wastewater (MWW), and potato and fruit wastes, reducing environmental contamination and decreasing energy consumption and treatment costs. This review focuses on recent advancements regarding the design, configuration, and operation mode of MFCs, as well as their capacity to produce bioelectricity (e.g., 2203 mW/m2) and fuels (i.e., H2: 438.7 mg/L and CH4: 358.7 mg/L). Furthermore, this review highlights practical applications, challenges, and the life-cycle assessment (LCA) of MFCs. Despite the promising biotechnological development of MFCs, great efforts should be made to implement them in a real-time and commercially viable manner.

“…However, to ensure the effective operation of the DF-MEC process, many auxiliary processes (e.g., centrifugation, dilution, and pH adjustment) must be applied, thereby making the whole process more complicated [5]. To overcome the bottlenecks of the two-stage process, a single-stage DF and MEC, namely, sDFMEC, has recently been proposed [13][14][15][16]. With sDFMEC, both the DF and MEC processes can maintain their advantages in a single reactor, providing the maximal yield of 12 mol-H 2 /mol-glucose from a variety of organic sources, while significantly reducing expenditures when compared to two-stage systems [14].…”

“…Besides, various issues of sDFMEC, such as poor purity of produced H 2 due to methane (CH 4 ) cogeneration and ineffective energy recovery, have not been properly overcome [11,13]. Specifically, the coexistence of unwanted microorganisms can considerably reduce the efficiency of sDFMEC [14][15][16]. For instance, electrotrophic methanogens compete directly with the hydrogen evolution reaction (the main reaction for H 2 production at the cathode of sDFMEC), which reduces protons and electrons for CH 4 formation [18], as shown in Eq.…”

The production of hydrogen (H2) from water hyacinth (WH) can contribute to reducing both the negative impact of WH on ecosystems and dependence on fossil fuels. In this study, the combination of dark fermentation (DF) and microbial electrolysis cell (MEC) in a single reactor, namely, sDFMEC, was investigated to improve the H2 productivity of WH. Furthermore, the intermittently applied voltage (I-Eapp) scheme and various methane (CH4) inhibition methods, including air exposure, heat treatment, and chloroform (CHCl3) addition, were applied for performance enhancement purposes. The findings indicated that with a sufficient duty time of external energy input (less than 1 hour), the intermittent mode can enhance the performance of WH-fed sDFMEC but does not significantly inhibit CH4 formation. While air exposure and heat treatment damaged both methanogens and exoelectrogens, lowering sDFMEC performance, additional CHCl3 showed the best selective and long-term inhibition on methanogens (over 350 operation hours without further addition). Overall, the combination of the I-Eapp scheme and CHCl3 applied in WH-fed sDFMEC achieved a yield of 670.1 ± 15.2 mL − H 2 / g − VS , around 160% higher than the normal condition.

“…Currently, hydrogen is mainly used for the production of ammonia (53% of the total) [10]. SMR is the main method for hydrogen production due to the high availability of methane and the higher economic potential when compared to that of other cleaner processes for hydrogen production, such as conventional electrochemical technologies (electrolysis [11][12][13], cold/hot plasma [14][15][16], photoelectrochemical [17][18][19]), [20,21]. In SMR, CO2 is the main byproduct.…”
