Summary The performance of allotrope carbon materials has been explored because of their superior properties in energy system applications. This review provides an understanding of the current work focusing on the applications of selected carbon materials in important energy systems, focus on thermal interface materials (TIMs), and fuel cell applications. This article begins with the introduction of TIMs and fuel cell in general working principle and presents details on carbon materials. The discussion focuses on updates from the latest research work and addresses current challenges and opportunities for research toward TIMs and fuel cell applications. The optimum performance of TIMs was seen when thermal conductivity achieved at a maximum of 3000 W (m K)−1 by using vertically aligned carbon nanotubes (CNTs) and a minimum internal thermal resistance of 0.3 mm2 K W−1. Meanwhile for fuel cell, the platinum/CNTs catalyst applied proton exchange membrane fuel cell achieved high power density of 661 mW cm−2 in the presence of Nafion electrolyte membrane. This review provides insights for scientists about the use of carbon materials, especially in energy system applications.

“…Recently, we have reported graphene-containing fibrous structures formed by electrospinning [28,29]. In literature, there are several studies about graphene hybrid supports for Pt, yet, to the best of our knowledge, hybrid structure was formed by mechanical mixing of Pt/graphene electrocatalyst with pristine carbon black or commercial Pt/CB and graphene [26,30]. However, in our study, Pt/partially reduced graphene oxide (rGO)/CB electrocatalysts were synthesized by mechanical homogenizing of carbon components (rGO and CB).…”

Here, we report a novel electrode structure with graphene and graphene-carbon black hybrids by electrospraying for polymer electrolyte membrane fuel cells. After syntheses of platinum (Pt)/partially reduced graphene oxide (rGO) and Pt/r-GO/carbon black (CB) hybrid electrocatalysts, suspensions of synthesized electrocatalyst inks were prepared with Nafion Ò ionomer and poly(vinylidene fluoride-cohexafluoropropylene) and electrosprayed over carbon paper to form electrodes. Electrosprayed catalyst layer exhibited uniform and small size Pt distribution. As the graphene content increases micrometer-sized droplet, pore formation and surface roughness of the electrode increase. Thus, an open porous electrode structure which is favorable for mass transport is achieved by electrospraying. The maximum power densities, 324 mW cm -2 for Pt/rGO and 441 mW cm -2 for Pt/rGO/CB electrosprayed electrodes, were achieved at a relatively low catalyst loading.

“…Disordered graphitic carbon and crystalline graphite correspond to the D and G bands around 1350 cm À1 and 1590 cm À1 in Raman spectra, respectively. 44,45 Therefore, the ratio of D band to G band (I D /I G ) was calculated to evaluate the degree of defect for the pyrolyzed catalysts. The I D / I G ratio of SS (I D /I G ¼ 1.00) is lower than that of ASS (I D /I G ¼ 1.03), NASS (I D /I G ¼ 1.06), CoASS (I D /I G ¼ 1.05) and CoNASS (I D / I G ¼ 1.18).…”
