“…Moreover, its maximum output power density outperforms many fuel cells such as direct photosynthetic biofuel cell (5.26 μW cm −2 ), microbial fuel cell (5.5 μW cm −2 ), glocuse fuel cell (1.45 and 230 μW cm −2 ), ascorbic acid fuel cell (1.83 μW cm −2 ), biofuel cell (120, 7.9, and 34.3 μW cm −2 ), enzymatic biofuell cell (12.5, 34.1, and 121 μW cm −2 ), and so forth (Figure 4j). [63][64][65][66][67][68][69][70][71][72] It should be noted that the carbon cloth used in FDUFC is a similar material to the gas diffusion layer in traditional proton exchange membrane fuel cell, while it has excellent mechanical and flexibility properties. It is desirable to use Ni foam as a support because it has a three-dimensional network structure, which exposes more active sites and ensures effective gas bubble release and electron/mass transfer.…”

The efficiency of many clean technologies, such as urea fuel cells, hydrogen production from urea-containing water splitting, and sewage treatment, and so forth, is restricted due to the sluggish kinetics of the urea oxygen reaction (UOR). Mo-doped Ni-based catalysts are excellent for UOR because of the synergistic effect between Ni and Mo. However, such applications have indeed been hampered by a lack of mechanistic comprehension. Here, we fabricate Mo-Ni(OH) 2 nanosheets for efficient UOR electrocatalysis with activity at least twice higher than Ni(OH) 2 nanosheets. Various in situ characterizations including Raman, differential electrochemical mass spectrometry and Fourier transform infrared spectroscopy reveals that the doping of Mo lowers the onset potential required for Ni 2+ /Ni 3+ conversion and promotes the coupling of the N-N bond inside the molecule and the fracture of the double bond between C and O in the urea molecule. In addition, an entirely flexible direct urea fuel cell with the Mo-Ni(OH) 2 electrocatalyst delivers a maximum output power density of 0.78 mW cm −2 and complete flexibility for the first time. Our research significantly promotes the mechanistic understanding of UOR electrocatalysis and its applications.

“…The bilirubin oxidase enzyme used in this study increased the half-life by 5 hours. Kuroishi et al [69] used a modified electrode using the graphene-coated carbon fiber to help solve insufficient oxygen dissolved in the fuel liquid. Using graphene-coated carbon fiber with high porosity and surface area allowed the permeability of the oxygen gas to reach the electrode surface.…”

Enzymatic biofuel cells (EBFCs) is one of the branches of fuel cells that can provide high potential for various applications. However, EBFC has challenges in improving the performance power output. Exploring electrode materials is one way to increase enzyme utilization and lead to a high conversion rate so that efficient enzyme loading on the electrode surface can function correctly. This paper briefly presents recent technologies developed to improve bio-catalytic properties, biocompatibility, biodegradability, implantability, and mechanical flexibility in EBFCs. Among the combinations of materials that can be studied and are interesting because of their properties, there are various nanoparticles, carbon-based materials, and conductive polymers; all three have the advantages of chemical stability and enhanced electron transfer. The methods to immobilize enzymes, and support and substrate issues are also covered in this paper. In addition, the EBFC system is also explored and developed as suitable for applications such as self-pumping and microfluidic EBFC.
