“…Degradation rates for each exposure series were determined by applying both a linear model and a one-phase decay model in the form of Eq. [3], where V is the potential at time t, P is a plateau value at infinite t, k is the rate constant, and V 0 is the initial potential:…”

“…The generated syngas is converted into electrical energy by subsequent combustion in a gas turbine [1] or electrochemical reaction in a fuel cell. [2][3][4][5] In particular, coupling a solid oxide fuel cell (SOFC) to a gasification process increases the overall cycle efficiency from 39.5 to 45.0 pct [6] or even greater when utilizing anode gas recycling. [7] The fuel cell (FC) emits low levels of NO X and SO X and facilitates the separation of CO 2 from the exhaust stream for eventual sequestration.…”

Energy generation strategies demonstrating high efficiency and fuel flexibility are desirable in the contemporary energy market. When integrated with a gasification process, a solid oxide fuel cell (SOFC) can produce electricity at efficiencies exceeding 50 pct by consuming fuels such as coal, biomass, municipal solid waste, or other opportunity wastes. The synthesis gas derived from such fuel may contain trace species (including arsenic, lead, cadmium, mercury, phosphorus, sulfur, and tars) and low concentration organic species that adversely affect the SOFC performance. This work demonstrates the impact of exposure of the hydrocarbons ethylene, benzene, and naphthalene at various concentrations. The cell performance degradation rate is determined for tests exceeding 500 hours at 1073 K (800°C). Cell performance is evaluated during operation with electrochemical impedance spectroscopy, and exposed samples are postoperationally analyzed by scanning electron microscopy/energy dispersive spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. The short-term performance is modeled to predict performances to the desired 40,000-hours operational lifetime for SOFCs. Possible hydrocarbon interactions with the nickel anode are postulated, and acceptable hydrocarbon exposure limits are discussed.

“…Copper (Cu) is well known for such a replacement which is being used alone or in combination with Ni anodes in obtaining bimetallic electrodes [3]. Even though the catalytic activities for the formation of C-C bonds is not in the expected range, Cu provides the required electrical conductivity for the anodes in comparison with Ni [7,8].…”

“…In ceria-based cermets, the ceramic phase (regardless the type of metal) not only exhibits high ionic conductivity (between 600 and 800 °C), but also is an excellent catalyst for hydrocarbon oxidation [7,8]. These kind of anodes have demonstrated effective behavior with a variety of hydrocarbon fuels, and are highly resistant to deactivation by carbon deposition, even considering the direct conversion of hydrocarbons without prior reform in CO and H 2 [9].…”

An in situ one step synthesis route based on the polymeric precursor method was used to produce dual phase CuO-samaria doped ceria (SDC) nanocomposite powders. This chemical route allowed to obtain composite powders with reduced particle size and uniform distribution of Cu, Ce and Sm elements. The particulate material was characterized by powder X-ray diffraction (XRD) combined with Rietveld refinement. CuO-SDC sintered in air between 950 to 1050 °C and subsequently reduced to Cu-SDC cermets were further characterized by XRD and scanning electron microscopy. The open porosity was measured using the Archimedes' principle. Suitable microstructures for both charge transfer and mass transport processes (30 to 45% porosity) were attained in Cu-SDC cermets previously fired at 1000 to 1050 °C. Overall results indicated that CuO-SDC composites and Cu-SDC cermets with potential application as anodes for solid oxide fuel cells (SOFCs) can be obtained by microstructural design. An anode supported half-cell was prepared by co-pressing and co-firing gadolinia doped ceria (CGO) and the herein synthesized CuO-SDC nanocomposite powder.

Summary At present with the massive induction of distributed renewable energy sources (RES), energy storage systems (ESS) have the potential to curb the intermittent nature of micro sources and provide a steady supply of power to the load. It gives an optimum solution and considers as a major part of intelligent grids. For making a green environment, Electric Vehicle (EV) is the best option that emits zero exhaust gases, cleaner, less noisy and eco‐friendly compared to engine‐based vehicles. It could embark power sanctuary by allowing open access to RES. Nonetheless, EVs presently face encounters in the deployment of ESSs, inroad to their reliability, capacity, price, and online management issues. This study comprehensive review about technical advancements of ESSs, its detailed taxonomy, features, implementation, possibilities with system differences, and additional features of particularly EV applications. Hence, in this current study, technical analysis of Energy storage systems, its leading technologies, core assets, global energy stakeholders, economic merits and techniques on energy conversion is provided. Besides, the way of deploying energy storage techniques, the barriers and assessments are also presented to give a wider scope in this particular area.
