“…The breakdown of substrates usually results in the production of hydrogen gas and oxygen (23). Once hydrogen and oxygen is released as product, they are utilized by fuel cells to generate electricity and water as byproduct, water can again be used by microbes and this cycle goes on until all the substrate is consumed or until the microbes reach their maximum conversion rate (21,24).…”

With the quick progress in technology and microengineering, point-of-care and personalized care, supported wearable and implantable medicine are changing into a reality. Both microbial fuel cells and enzymatic fuel cells hold a very good potential to power such devices using biochemical fluids as fuel. For a long time, the path to implant safe and efficient medical devices has been around but it still has a long way to go, although there is a certain amount of progress in technologies and scientific fields. One of the aspects of implantable medical devices that required attention is the power supply. The use of biofuel cells can become an alternative to supplying power to certain implantable medical devices instead of using batteries. Biofuel cells, their understanding, design, and compatibility are gaining importance as batteries are required to be charged and some batteries are even nonchargeable. The major issue associated with the implementation of biofuel cells is the integration of the implantable devices with the biofuel cells, adequate power supply, and biocompatibility. This review paper summarizes the working principle of enzymatic/microbial fuel cells, their applications, and provides an insight into the advances in their use in powering wearable and implantable devices. It highlights the various stages involved in the development of implantable fuel cells capable of generating power to run different implantable medical devices.

“…There is much growing interest to secure energy sustainability and clean environment through the emergent technologies in biomass conversion to renewable fuels. Gasification of biomass feedstock at elevated temperatures and then subjecting it to reforming process is capable of producing hydrogen and other related gases such as CO 2 CO, CH 4 and H 2 O reformates that offer many industrial applications in the production of value‐added chemicals and energy such as fuel cell technology (Aasberg‐Petersen et al, 2011; Moradian et al, 2021; Pandey, 2019). Solid oxide fuel cells (SOFCs) operate at high temperature and are very flexible to choice fuel, hence capable of utilizing these gases as alternative fuel to its conventional fossil‐based hydrogen when compared other fuel cell technologies that operate at low temperatures (Hibino et al, 2021; Pongratz et al, 2022).…”

Catalytic steam reforming of renewable feedstock to renewable energy or chemicals always goes with intense coking activities that produce carbonaceous products leading to low performance and eventual catalyst deactivation. Supported metal catalyst such as Ni/Al 2 O 3 is known to catalysed gasification and decomposition of biomass feedstock largely for renewable fuel production with promising results. Catalyst deactivation from high carbon deposition, agglomeration and phase transformations resulting to rapid deactivation are some of the issues identified with the use of the catalyst. In this work, improvement on the coke resistance and catalytic properties of Ni/Al 2 O 3 catalyst is sought via the use of a thermally stable and coke-resistant perovskite La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3-δ (LSCM) as catalyst promoter/modifier and involving Zirconia-doped Ceria (Ce-Zr) as alternative support in steam reforming of pure and by-product glycerol. The stabilizing influence of the LSCM on the Ni catalyst has improved stability against agents of deactivation with a consequent significant improvement of catalytic activity of Ni/Al 2 O 3 in H 2 production and robust suppression of carbon deposition. Particularly, the synergy between the LSCM promoter and alternative Ce 0.75 Zr 0.25 O 2 support enhanced the basic and redox properties known for Ce 0.75 Zr 0.25 O 2 support in contrast to the week acid centres in γ-Al 2 O 3 support which further improved nickel stability, catalystsupport interaction with a resultant high catalytic activity and robust coke suppression as a result of enhanced oxygen mobility. There is correlation between the product distribution, nature of coke deposited and reforming temperature as well as type of support and structural modification. Hence, integration of a robust perovskite material as a catalyst promoter and choice of support could be tailored in design and development of robust catalyst systems to improve the performance of supported metal catalysts, particularly the suppression of carbon deposition for hydrocarbon and biomass conversion to renewable fuel or chemicals.

A Short Review on the Electrochemical Performance of Hierarchical and Nitrogen-Doped Activated Biocarbon-Based Electrodes for Supercapacitors

Cheap and efficient carbon electrodes (CEs) for energy storage systems (ESS) such as supercapacitors (SCs) and batteries are an increasing priority issue, among other things, due to a globally increasing share of intermittent electricity production (solar and wind) and electrification of transport. The increasing consumption of portable and non-portable electronic devices justifies research that enables environmentally and economically sustainable production (materials, processing techniques, and product design) of products with a high electrochemical performance at an acceptable cost. Among all the currently explored CEs materials, biomass-based activated carbons (AC) present enormous potential due to their availability and low-cost, easy processing methods, physicochemical stability, and methods for self-doping. Nitrogen doping methods in CEs for SCs have been demonstrated to enhance its conductivities, surface wettability, and induced pseudocapacitance effect, thereby delivering improved energy/power densities with versatile properties. Herein, a short review is presented, focusing on the different types of natural carbon sources for preparing CEs towards the fabrication of SCs with high electrochemical performance. The influences of ACs’ pore characteristics (micro and mesoporosity) and nitrogen doping on the overall electrochemical performance (EP) are addressed.
