The up-to-date research as far as it concerns the abiotic direct glucose fuel cells (DGFCs) is summarized and discussed in the present review. Platinum and goldbased as well as Raney-type electrocatalysts are among the most studied ones. In abiotically (non-implantable) DGFCs, unsupported Pt and PtRuO 2 , exhibited good activity (power density *20 mW cm -2 ), at room temperature and at atmospheric pressure. On the other hand, Au-based electrocatalysts adopted in a DGFC resulted in power densities up to ca. 5 mW cm -2 , exhibiting however high poisoning tolerance. Recently, after the introduction of alkaline membranes into the market, Pd-based electrocatalysts have attracted the attention of the research community because of their enhanced activity in alkaline media. However, there are still very few investigations where membrane electrode assemblies with palladium electrocatalysts have been applied. Moreover, Raney-type electrocatalysts, not yet examined for other fuels in direct polymer electrolyte fuel cells, are considered to be the most appropriate for implantable abiotic DGFCs. A novel implantable fuel cell in a human brain performed with 3.4 9 10 -3 lW power for 10 h adopting Raney-type electrocatalysts.

“…Most recently, the electrocatalytic glucose oxidation reaction has been of particular interest, which can be simultaneously applied for the elemental reaction in a direct glucose fuel cell (DGFC) [7][8][9], implantable fuel cell (IFC) [10,11], and glucose sensor [12][13][14]. For DGFC [7] and IFC [10], Pt is an active catalyst and is often employed as the anode to catalyze glucose oxidation.…”

“…Figure 10C presents the DGFC performances at different concentrations of glucose using Au/C synthesized from the BAE method as anode material [51]. The OCV is quite similar, 0.90V (±20 mV); P max = 0.86 (0.1 M), ) [74]. In addition, it outperforms the previous results from the electrodeposition method [44].…”

This chapter presents an overview on size, structure, morphology, composition as well as the effect of the support on the electrocatalytic properties of gold nanoparticles (AuNPs). It was found that the electrocatalytic properties of unsupported AuNPs strongly depend on their size and shape. Consequently, the electrocatalytic properties of AuNPs can be tuned. Furthermore, to design high-performance electrocatalysts with minimal precious metal content and cost, the direct immobilization of metal NPs onto carbon-based substrates during their synthesis constitutes another elegant alternative and has been thoroughly examined. These "easy-to-use" supports as scaffolds for AuNPs, namely carbon black, carbon paper, etc., offer beneficial contributions. Indeed, thanks to their high available surface area, good electronic conductivity and synergistic effect between the chemical species present on their surface and the loaded NPs, carbon-based supports enable maximizing the efficient utilization of the catalysts toward drastic enhancement in both activity and durability. We also examined different judicious combinations of (electro)analytical techniques for the unambiguous determination of the reaction product(s) over the Au-based nanocatalysts, using glucose as model molecule given its importance in electrocatalysis. The performances of carbonsupported AuNPs as anode materials in direct glucose fuel cell in alkaline medium were also discussed.
