<italic>Operando</italic> X-ray absorption spectroscopy (XAS) technique unravels that the CoFe nanoparticles in a new type of lanthana-anchored catalyst are nearly transformed into unique (Co/Fe)O(OH) under electrochemical condition, as real active species for oxygen evolution reaction.
A spherical PVC–MnO2 ion sieve of 2.0–3.5 mm diameter was prepared by the antisolvent method using synthesized Li4Mn5O12 ultrafine powder as precursor, poly(vinyl chloride) binder, and N-methyl-2-pyrrolidone solvent. Batch experiments adsorption capacity (isotherm) rate Li+ on were studied. Spherical had a high for Li+, isotherm data well fitted Langmuir model; kinetics described Lagergren equation. Furthermore, mathematical model set up to calculate film mass transfer coefficient (kf) pore...
Solid oxide electrolysis cells (SOECs) have great application prospects because of their excellent performance, but the long-term applications stacks are restricted by structural degradation under high-temperature conditions. Therefore, an SOEC model is developed and embedded in a process steam (HTSE) system to investigate influence stack at level. The sensitivity analysis optimization were carried out study factors hydrogen production efficiency search for optimal operating conditions...
Abstract A simulated interconnect/contact/cathode/cathode support test cell is fabricated to investigate the effectiveness of high‐entropy alloy as contact material on microstructure and performance converted spinel‐based layer. Although CuMnNiFeCo powder selected precursor, it showed good sinterability after sintering at 900°C for 2 h in air. The electrical layer evaluated by area‐specific resistance measurement, including isothermal exposure thermal cycling. compatibility with adjacent...
High temperature (HT) steam/CO2 coelectrolysis with solid oxide electrolysis cells (SOECs) using the electricity and heat generated from clean energies is an important alternative for syngas production without fossil fuel consumption greenhouse gas emissions. Herein, reaction characteristics outlet composition of HT under different operating conditions, including distinct inlet compositions current densities, are systematically studied at 800 °C commercially available SOECs. The process,...
Hydrogen production using solid oxide electrolysis cells (SOECs) is a highly efficient and low-carbon pathway to generate high purity hydrogen. However, working temperatures may result in thermal stress due mismatch the coefficient of expansion (CTE) between components with nonuniform temperature distribution. Serious concentration lead structural failure SOEC stack. Hence, this work investigated SOECs through three-dimensional planar unit model. A analysis method was proposed via...
A series of well-defined M–N–C based SACs (M = Fe, Ni, Co, Mn and Cu) was synthesized via a facile pyrolysis metal-doped ZIF-8 applied in electrocatalytic CO 2 reduction to CO. Fe–N–C possess highest activity for RR.
Different from low-temperature electrolysis systems, the large power consumption for balance of plant (BOP) reversible solid oxide cell (RSOC) system a high-temperature operating condition needs to be considered in determination capacity configuration hybrid renewable energy (HRE) system. To address this issue, power-based model RSOC is developed and corresponding strategy especially HRE also proposed paper. An optimization program composed wind turbines (WT), photovoltaic panels (PV),...
Solid oxide electrolysis cell (SOEC) industrialization has been developing for many years. Commercial materials such as 8 mol% Y2O3-stabilized zirconia (YSZ), Gd0.1Ce0.9O1.95 (GDC), La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF), La0.6Sr0.4CoO3−δ (LSC), etc., have used years, but the problem of mismatched thermal expansion coefficients various between cells not fundamentally solved, which affects lifetime SOECs and restricts their industry development. Currently, solutions reported, element doping,...
