“…AM technology, such as material extrusion, powder bed fusion, photopolymerization and binder jet, 65 can be used to create a fuel cell. 66 To perfect mass transport, charge transfer and electrochemical reactions, 65 the GDL can be prepared using a powder bed fusion method that includes selective laser sintering/selective laser melting and electron beam melting. 67 The disadvantages of these AM techniques are their high cost, poor penetrability and concentrated laser beam, making it difficult to sinter big areas or laminates.…”

A promising alternative to fossil fuel energy is the fuel cell technology. Proton exchange membrane (PEM) fuel cells are widely used in electric vehicle and mobile power generation fields. There are several components in the PEM fuel cell, namely the gas diffusion layer (GDL), PEM, catalyst layer (CL) and bipolar plate (BPP). The GDL is one of the key components of a PEM fuel cell and acts as a distributor of reagents, current conductor, water manager and a CL support. This paper presents an analysis of the materials and fabrication technologies of the GDL in the PEM fuel cell. A summary of the main materials for manufacturing the macroporous substrate (MPS) and microporous layer (MPL) of GDL was presented. Advanced manufacturing methods were described as single layer manufacturing, double layer manufacturing and multilayer manufacturing. A brief overview of the materials and manufacturing processes of BPP and CL were also presented. Future research directions have also been proposed.

“…AM facilitates the design for the assembly of MFCs, thereby mitigating mistakes as a result of human intervention and expediting the installation procedure. In a study by Zawadzki et al [98], AM techniques were also employed to construct an MFC with the incorporation of an exchangeable membrane slot. This enabled them to examine the effects of different separator membranes.…”

Extracellular electron transfer (EET) is a biological mechanism that plays a crucial role in various bioelectrochemical systems (BESs) and has substantial implications for renewable energy production. By utilizing the metabolic capacities of exoelectrogens, BESs offer a viable and environmentally friendly approach to electricity generation and chemical production; however, the diminished effectiveness of EET remains a hindrance to their optimal application in practical contexts. This paper examines the various strategies that have the potential to be employed to enhance the efficiency of EET systems and explores the potential for the integration of BESs technology with contemporary technologies, resulting in the development of an enhanced and sustainable system. It also examines how quorum sensing, electrode modifications, electron shuttles, and mediators can aid in improving EET performance. Many technological innovations, such as additive manufacturing, the science of nanotechnology, the technique of genetic engineering, computational intelligence, and other combinations of technologies that can be used to augment the efficacy of BESs are also discussed. Our findings will help readers understand how BESs, though an evolving technology, can play an important role in addressing our environmental concerns. Technical constraints are identified, and future directions in the field of EET are suggested.

Environmental pollution has been a continuous threat to sustainable development and global well-being. It has become a significant concern worldwide to combat the ecological crisis using low-cost innovative technologies. Biological oxygen demand (BOD) is a key indicator to comprehend the quality of water to guarantee environmental safety and human health; however, none of the present technologies are capable of online monitoring of the water at the source. Microbial fuel cells (MFC) are a promising technology for simultaneous power generation and wastewater treatment. MFCs have also been shown in fascinating applications to measure and detect the toxic pollutants present in wastewater. These are the bioreactors where exoelectrogenic microorganisms catalyze the conversion of the inherent chemical energy stored in organic compounds to electrical energy. Sensors employ energy conversion to measure BOD, which is considered an international index for the detection of organic material load present in wastewater. The MFC-based BOD sensors have gone through a wide range of advancement from mediator to mediator-less, double chamber to single-chamber, and large size to miniature. There have been detailed studies to improve the accuracy and reproducibility of the sensors for commercial applications. Additionally, multistage MFC-based BOD biosensors and miniature MFC−BOD sensors have also been ubiquitous in recent years. A considerable amount of work has been carried out to improve the performance of these devices by fabricating the proton exchange membranes and altering catalysts at the cathode. However, there remains a dearth for the fabrication of the devices in aspects like suitable microbes, proton exchange membranes, and cheaper catalysts for cathodes for effective real-time monitoring of wastewater. In this review, an extensive study has been carried out on various MFC-based BOD sensors. The efficiency and drawbacks associated with the different MFC-based BOD sensors have been critically evaluated, and future perspectives for their development have been investigated. The breadth of work compiled in this review will accelerate further research in MFC-based BOD biosensors. It will be of great importance to broad ranges of scientific research and industry.
