The development of cost-effective hydroxide exchange membrane fuel cells is limited by the lack high-performance and low-cost anode hydrogen oxidation reaction catalysts. Here we report a Pt-free catalyst Ru7Ni3/C, which exhibits excellent activity in both rotating disk electrode assembly measurements. mass specific as measured experiments, about 21 25 times that Pt/C, 3 5 PtRu/C, respectively. cell with Ru7Ni3/C can deliver high peak power density 2.03 W cm-2 H2/O2 1.23 H2/air (CO2-free) at...
Hydrogen is considered by many to be a promising energy currency, particularly for the transportation sector and mobile devices. To realize hydrogen-based fuel economy, hydrogen must produced in an efficient sustainable manner. In this article, single-layer nickel hydroxide (Ni(OH)2)-nanosheet-assisted Pt/C catalysis evolution reaction (HER) alkaline environment was investigated. The HER activity trajectories of hybrid catalysts correlation with composition morphology Ni(OH)2 were explored...
Hydroxide exchange membrane fuel cells (HEMFC) are a promising power source for automobiles due to their low cost. Here we focus on improving the beginning-of-life performance of HEMFCs higher level with poly(aryl piperidinium) (PAP) membranes and ionomers. We find that lower RH backpressure in anode than cathode can eliminate flooding dryout so balanced water management be achieved. also PtRu/C is better catalyst Pt/Ketjen Black presence Ru Pt/Vulcan XC-72 its mass transport properties....
Dearomative 1,3-dipolar cycloadditions of 1-Boc-pyrroles with in situ generated silver α-bromo alkylidenenitronates delivered a series 3 ,6 -dihydro-4-Boc-pyrrolo[2,3- d ]isoxazole-2-oxides (17–91% yields) under very mild conditions.
Hydroxide exchange membrane fuel cells (HEMFCs) are a potentially lower-cost hydrogen cell technology; however, ambient levels of CO 2 in air significantly reduce HEMFCs’ performance. In this work, we demonstrate an electrochemically-driven separator (EDCS) which can be used to remove from upstream the HEMFC stack vehicles, protecting it -related performance losses. The EDCS operating window was explored for current density, anode flow, and cathode flow with respect its impact on separation...
Alkaline pretreatment is perceived as an essential step for high-performance hydroxide exchange membrane fuel cells (HEMFCs), but its exact function not fully understood. Here we show that alkaline only necessary when carboxylates are generated from platinum- or palladium-catalyzed oxidation of primary alcohol solvents during electrode assembly (MEA) fabrication. When needed, bicarbonates a better choice than the most commonly used bases. We further demonstrate MEAs with Pt/Pd-free...
For the treatment of 2-naphthol wastewater, homogeneous electro-Fenton process was considered as an effective method but some disadvantages greatly restrict its application. The three-dimensional (3D-EF) system using a nano zero-valent iron-supported biochar (NZVIs-BC) particle electrode and Cu-supported stainless steel (Cu-SSE) proposed to avoid electro-Fenton. In this work, 3D-EF developed, which consisted Cu-SSE (cathode), graphite rod (anode) NZVIs-BC electrode. effect ratio ferrous...
This study employs logging, petrology, and geochemistry to investigate the characteristics, origin, hydrocarbon significance of fractures (ferro) dolomite veins in a buried hill Qiongdongnan (QDN) Basin, South China Sea. We show that area is mainly characterized by three stages fracturing with medium-high dipping angles. The orientation NNW–SSE, consistent fault system strike formed Mesozoic–Cenozoic tectonic activity basin. (Ferro) can be classified into stages, all which even observed...
The deployment of large language models (LLMs) in diverse applications requires a thorough understanding their decision-making strategies and behavioral patterns. As supplement to recent study on the Turing test, this paper presents comprehensive analysis five leading LLM-based chatbot families as they navigate series economics games. By benchmarking these AI chatbots, we aim uncover document both common distinct patterns across range scenarios. findings provide valuable insights into...
The performance of a hydrogen-powered, electrochemically-driven CO 2 separator (EDCS) was demonstrated at cathode inlet concentrations from 400 ppm to 5,000 ppm. impact current density and concentration were evaluated predict operating windows for various applications. single-cell data used scale 100 cm , multi-cell stack using shorted-membrane design four applications: direct air capture (DAC), hydroxide exchange membrane fuel cell (HEMFC) pretreatment, submarine life support, space...
