چکیده
Solid oxide electrolyser (SOE) technology can become a key player in energy systems, with increasing shares of electricity from fluctuating sources such as wind and solar, contributing to power grid balance storage well providing green fuels for transportation. Most mature SOE configurations are electrolyte supported or fuel electrode supported. Metal cell an interesting concept decreasing costs robustness. The present study compares metal cells terms performance durability under conditions. Special emphasis was on medium temperature operating conditions 650 °C. cells, fabricated using ceramic processing methods, showed better compared state-of-the-art (SoA) Ni/YSZ configuration, by tape casting screen printing, steam electrolysis at 700 area specific resistance (ASR) lower ca. 20% the 50% H2O H2 vs. air Furthermore, stable performance—even slight activation—during long-term tests over 500 h °C ?0.25 ?0.5 A/cm2, while SoA reference degraded 13%/1000 same

Molten Carbonate Fuel Cells for Electrolysis
The molten carbonate fuel cell (MCFC) has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis (MCEC), it provides a promising option for producing fuel gases such as hydrogen, via water electrolysis, and syngas, via co-electrolysis of water and carbon dioxide. The molten carbonate cell can thereby operate reversibly as a dual energy converter for...
متن کاملElectrolyte Degradation in Anode Supported Microtubular YSZ-based Solid Oxide Steam Electrolysis Cells at high voltages of operation
Degradation of solid oxide electrolysis cells (SOECs) is probably the biggest concern in the field of high temperature steam electrolysis (HTSE). Anode supported, YSZ-based microtubular solid oxide fuel cells (SOFC) have been tested in fuel cell mode and also at high voltages (up to 2.8V) under electrolysis mode. At high steam conversion rates the cell voltage tends to saturate. Our hypothesis ...
متن کاملSupported Liquid Membrane in Metal Ion Separation: An Overview
Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...
متن کاملMolecular Design of Supported Metal Oxide Catalysts
This study demonstrates that molecular design of supported metal oxide catalysts is possible from molecular level information obtained from combined Raman spectroscopy and the methanol oxidation reaction. The important factors that influence the molecular design of the supported metal oxide catalysts are the specific oxide support (factor of -10,) and the specific sur-face metal oxide (factor o...
