This study employs density functional theory (DFT) at the MN12-SX/GenECP/Def2svp/LanL2DZ computational method to investigate the electronic, structural, and catalytic properties of modified fullerene (C₆₀) systems encapsulated with palladium (Pd) and doped with transition metal carbides: CrC, FeC, MnC, TiC, and VC. Frontier molecular orbital (FMO) analysis reveals significant changes in the HOMO-LUMO gap upon doping, indicating enhanced electronic conductivity essential for catalytic activity. The lowest energy gaps 0.081 eV for MnC–Pd@C₆₀ and 0.096 eV for VC-Pd@C₆₀ were observed thus showing their readiness in terms of electron transfer. HER activity was assessed through the calculation of Gibbs free energy changes (ΔG_H) for hydrogen adsorption. The results highlight TiC–Pd@C₆₀, FeC–Pd@C₆₀, and CrC–Pd@C₆₀ as having optimal ΔG_H values close to zero, suggesting their superior catalytic performance. Structural analysis confirms the stability of these doped systems, with minimal distortions observed in the fullerene framework upon metal encapsulation and doping. Vibrational analysis revealed that Pd@C₆₀ complexes show reduced M − C vibrations and the formation of M − H bonds, indicating efficient hydrogen adsorption, especially in MnC–Pd@C₆₀ and VC-Pd@C₆₀. Thermodynamics investigation show MnC–Pd@C₆₀ and VC-Pd@C₆₀ to exhibit highly exothermic and spontaneous hydrogen adsorption. Overall, Ti, Fe, and Cr-based catalysts show weaker interactions, which might favor the desorption step in HER. On the other hand, catalysts with V and Mn show strong hydrogen interactions via the Tafel step, which might benefit initial hydrogen adsorption but could require optimization to ensure efficient hydrogen release.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"97 ","pages":"Pages 1-10"},"PeriodicalIF":8.1,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigation encompasses coating structure, surface morphology, corrosion resistance, surface wettability, in-plane electrical conductivity, and interfacial contact resistance. X-ray diffraction and X-ray photoelectron spectroscopy confirm the presence of Cr₂SiC coatings on SS316L, while energy-dispersive X-ray spectroscopy verifies uniform coverage and elemental weight percentage. Corrosion resistance is evaluated using potentiostatic and potentiodynamic polarization tests, showing excellent resistance with low corrosion current density (I_corr) at both 25 °C (3.29E-03 μA/cm²) and 80 °C (4.32E-02 μA/cm²), meeting US Department of Energy (DOE) technical targets. Potentiodynamic polarization reveals large corrosion potential and small I_corr values at both temperatures, outperforming uncoated samples. Electrochemical impedance spectroscopy post-accelerated corrosion tests show high charge transfer resistance at 25 °C (3.68E+05 Ω cm²) and 80 °C (3.02E+05 Ω cm²), indicating stability in acidic environments. Surface wettability analysis indicates low water affinity with a large contact angle (75°) and low surface free energy (28.92 mJ/m²) for the coated samples as compared to the uncoated samples. Electrical conductivity meets DOE targets with an in-plane conductivity of 4.59E+05 S/m and interfacial contact resistance of 8.04 mΩcm² after 5-h accelerated corrosion tests at 80 °C.

Hydrogen, as a critical yet complex energy vector, requires coordinated governance efforts to navigate its development effectively. To this end, we critically engage with key challenges facing the hydrogen sector and examine how institutional frameworks are addressing these issues. Departing from the broader scholarship on global energy governance, we conceptually leverage the socio-technical transition and innovation system literature to understand the complexities underpinning the development of the global hydrogen economy. We identify three overarching issue areas pertaining to the nature and role of hydrogen in the global energy system: end-use sector development, infrastructure and trade, and environmental and socio-economic sustainability. Each of these areas presents distinct challenges to hydrogen's global governance, from stimulating supply and demand to managing geo-economic challenges and establishing comprehensive certification and standards. Through mapping multilateral institutions at the global and regional levels and their main objectives, we offer insights into the emerging institutional architecture related to hydrogen and identify potential gaps in current governance. Our findings suggest that while newer, hydrogen-specific institutions complement the broader agenda of the main established international organizations, the overall global hydrogen structure remains a patchwork of diverse actors and frameworks, each addressing hydrogen-related challenges to varying degrees.

The successful operation of metal hydride energy storage systems depends on the properties of the metal hydrides employed, which vary with compositional changes. Therefore, in the present work, the influence of the substitution of Aluminium (Al), Manganese (Mn), and Tin (Sn) for Nickel (Ni) and Cerium (Ce) for Lanthanum (La) on LaNi₅ properties is studied in terms of hydrogen storage capacity (HSC), reaction enthalpy, working temperature, and pressure, and consequently on metal hydride energy storage system performance. The metal hydride properties were measured through the volumetric method using an in-house Sievert's Apparatus, and it was observed that the hydrogen storage capacity and equilibrium pressure are higher in the case of Cerium (1.48 wt%, 6.26 bar) substitution than those for Aluminum (1.43 wt%, 0.81 bar), Manganese (1.44 wt%, 0.9 bar), and Tin (1.4 wt%, 0.17 bar) at 20 °C. In contrast, the opposite trend was observed for reaction enthalpies. These metal hydride properties are applied to estimate the thermodynamic performance of metal hydride energy storage systems operating at 25 °C, 100 °C, 130 °C, and 150 °C using the metal hydride combination of La_0.9Ce_0.1Ni₅ – LaNi_4.7Al_0.3, LaNi_4.7Mn_0.3 – LaNi_4.7Sn_0.3 and La_0.9Ce_0.1Ni₅ – LaNi_4.7Sn_0.3.

To obtain better temperature distribution within the PEMFC stack, the cooling plate configuration of PEMFC and the manifold height of the stack have been optimized based on the impacts of configuration structure and the coolant dynamics in the present article upon validated models. The study found that the coolant rate increase made the temperature more consistent across the cooling plate's surface and the membrane. Except for the cooling plates with a single serpentine channel, the other five designs achieved their lowest level of temperature inconsistency at a cell pressure drop of less than 800. The mixed serpentine channel (V–I) design showed the best consistency. As the electric current in the stack goes up, the heat increases, which approximates exponential growth, and the increase in current density enlarges the temperature difference between the membrane and the cooling plate. Among the six cooling plate designs, the V–I cooling plate showed the most consistent temperature distribution, which is good for the fuel cell stack's lifespan. When the manifold height decreases, the coolant speed in all manifolds increases. A higher manifold height leads to a more noticeable improvement in cell consistency. The impact of the variation between single cooling plates is more evident at low cooling water flow rates. Among all the channels in the cooling plate designs, stacks under the single serpentine design showed the lowest variations at a constant pressure drop.
