“…It can be found clearly that the DBFC with the Ni-np@NC/C anode delivers the highest peak power density of 218 mW cm –2 , while those with Ni/C and Pt/C are only 65 mW cm –2 (Figure S10) and 90 mW cm –2 , respectively. In addition, it can be viewed in Figure b that the performance of the DBFC using the Ni-np@NC/C anode is comparable or better than that of DBFCs with noble metal catalyst anodes reported in the literatures. ,,,− Its energy density can reach 1046 W h kg –1 , much higher than that of using Ni/C anode (82 W h kg –1 ), confirming once again that Ni-np@NC/C possesses excellent catalytic activity to BOR. The operation stability is also a crucial aspect to evaluate DBFC performances in practical application.…”

A porous Ni–Cu alloy dendrite catalyst covered by Ni nanoparticles (Ni-np@NC) has been fabricated by an ultrafast and controllable strategy. The research results show that the morphology of the Ni–Cu alloy depends strongly on the Cu2+concentration. Moreover, the Ni-np@NC catalyst demonstrates excellent selectivity and activity toward the borohydride oxidation reaction (BOR). Furthermore, on the Ni-np@NC catalyst electrode, the overpotential merely requires 169 mV at a current density of 10 mA cm–2 for BOR, and the fuel efficiency may reach 70%. The direct borohydride fuel cell using the Ni-np@NC/C anode can export a maximum power density of 218 mW cm–2, much higher than that using the noble-based anode reported in the literature. The remarkable enhancement of Ni-np@NC catalyst performances is on the back of the unique morphology of porous dendrite covered by nanoparticles and the introduction of Cu.

“…The loading of metal catalysts on carbon-based materials increases the electrocatalytic activity for glucose oxidation [14][15][16]. As a catalyst support material, CNTs have superior properties such as large surface area, electrochemical stability, and high electrical conductivity [17,18]. CNTs can decrease the cost while improving the catalytic activity and stability of electrocatalysts [19].…”

Fuel cells are the most promising alternative green and clean energy source in the future because of their low carbon emissions. Fuel cells have been employed in various applications, including large-scale stationary power generation, distributed combination heat and power, transport, and mobile and stationary applications. Generally, a fuel cell system consists of a proton exchange membrane or polymer electrolyte membrane (PEM), a catalyst layer, a microporous layer, a gas diffusion layer, and a bipolar plate at the anode and cathode. PEMs are an important component in fuel cell applications that act as proton carriers and separators for the anode and cathode, while catalyst support materials are a major component of proton exchange membrane fuel cell. The membrane and catalyst affect the cost, durability, and electrochemical activity of fuel cells. Researchers have made serious attempts to develop materials that can reduce the cost of membrane and catalyst manufacturing, lowering the overall cost of fuel cells. Because of its unique features like 2D structure, ease of fabrication, and low production cost, graphitic carbon nitride (g-CN or g-C 3 N 4 ) is now frequently mentioned.Due to their exceptional qualities, carbon-based materials are also commonly used in a variety of applications, including fuel cells. The effectiveness of experiments using g-C 3 N 4 , carbon nanotube (CNT), and graphene as essential materials in enhancing fuel cell performance is discussed in this study. This review, primarily for fuel cell applications, discusses ways of adjusting the structure in terms of porosity, dimension tailoring, and atomic and edge functionalization. The study also involved the properties of composite materials as well as their respective applications on membranes as well as fuel cell catalysts. This review is useful for investigations into g-C 3 N 4 , CNT, and graphene because it offers ideas and direction for improving the potential of associated systems, including fuel cells, hydrogen production, solar cells, batteries, and supercapacitors.Abbreviations: CHP, combination heat and power; CNT, carbon nanotube; DMFC, direct methanol fuel cell; g-CN or g-C 3 N 4 , graphitic carbon nitride; MEA, membrane electrolyte assembly; ORR, oxygen reduction reaction; PEM, polymer electrolyte membrane; PEMFC, proton exchange membrane fuel cell; SPEEK, sulfonated poly (ether ether ketone).
