“…The commonly used substrate is carbon cloth [44], carbon paper [45], indium tin oxide (ITO) [22], glassy carbon electrode [46], and buckypaper [47], because these carbon-based materials provide advantages such as high compatibility, being user-friendly, and being environmentally friendly and made of reusable material [40], through physical adsorption or chemical bonding to form the carbon composites [39]. Substrates are rarely studied in EBFCs, but Shen et al [48], using graphene paper [49], used the reduction method followed by crosslinking to strengthen the mechanical stability of the material and used it for the anode and cathode in the EBFC, as shown in Figure 3. In the EBFC system developed, authors use pyrroloquinoline-dependent glucose dehydrogenation (PGG-GDH) and bilirubin oxidase (BOx) as the enzyme anode and cathode.…”

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.

The electrode material is a pivotal component in achieving efficient electron transfer in an enzymatic biofuel cell (EBFC). Herein, novel hydrophilic carbon fibers (HCFs) with a helical structure are synthesized through chemical vapor deposition and are used as an electrode material for the immobilization of biocatalysts to fabricate bioelectrodes, where glucose dehydrogenase, serving as the anodic enzyme, is co-immobilized with 1,4-naphthoquinone on the HCFs for the catalysis of the glucose oxidation reaction (GOR), and bilirubin oxidase, as the cathodic enzyme, is co-immobilized with protoporphyrin IX for the catalysis of the oxygen reduction reaction (ORR). It is found that thermal annealing the HCFs improves the bioelectrocatalytic performances of the as-fabricated bioanode for the GOR and biocathode for the ORR, owing to the enhanced electron transfer kinetics. Subsequently, a membraneless glucose/O 2 EBFC assembled by using the as-synthesized bioelectrodes is able to generate a high open circuit voltage of 0.8 V and a maximum power density of 0.7 mW cm À 2 at 0.44 V with good operational stability. The practicability in fabricating membraneless EBFCs makes the synthesized HCFs promising in miniature bioenergy devices.

“…[24][25] Graphene can be produced by reduction of graphite derived graphene oxide (GO), resulting in reduced graphene oxide (RGO) with unique biocompatibility due to the presence of residual surface hydroxyl and carbonyl groups. To enable a wide application of bioelectrodes in implanted or flexible electronic devices, three-dimensional (3D) or free-standing graphene based electrodes, such as graphene foam, [26][27] crumbled graphene, 28 and graphene paper [29][30][31] have emerged recently as promising electrode candidates. Among these, graphene papers with high flexibility and conductivity have been utilized to immobilize enzymes such as glucose dehydrogenase and BOD.…”

Enzyme immobilization using nanomaterials offers new approaches to enhanced bioelectrochemical performance and is essential for the preparation of bioelectrodes with high reproducibility and low cost. In this report, we describe the development of new three-dimensional (3D) bioelectrodes by immobilizing a "bioink" of glucose oxidase (GOD) in a matrix of reduced graphene oxides (RGOs), polyethylenimine (PEI), and ferrocene carboxylic acid (FcCOOH) on carbon paper (CP). CP with 3D interwoven carbon fibers serves as a solid porous and electronically conducting skeleton, providing large surface areas and space for loading the bioink and diffusion of substrate molecules. RGO enhances contact between the GOD-matrix and CP, maintaining high conductivity. The composition of the bioink has been systematically optimized. The GOD bioelectrodes show linearly increasing electrocatalytic oxidation current towards glucose concentration up to 48 mM. A hybrid enzymatic biofuel cell equipped with the GOD bioelectrode as a bioanode and a platinum cathode furthermore registers a maximum power density of 5.1 μW cm -2 and an open circuit voltage of 0.40 V at 25 °C.The new method reported of preparing a bioelectrode by drop-casting the bioink onto the substrate electrode is facile and versatile, with the potential of application also for other enzymatic bioelectrodes.
