Chapter 6. Molybdate Based Ceramic Electrode Materials 176 (6.1) The additional requirements of any solid oxide cell electrode (which are applicable to ceramic electrodes as well) include: Thermodynamic stability in operating conditions (gas atmospheres and temperature range) Dimensional stability in operating conditions Thermal expansion compatibility with the electrolyte material Chemical compatibility with the electrolyte and other materials during operation, e.g. the electrode and electrolyte do not react and form undesirable phases Chemical compatibility with the electrolyte and other materials during fabrication Finally, it is important to note that recently developed methods of preparing electrodes with new types of microstructures can effectively bypass some of the criteria of the two lists above. For example, a porous backbone structure can be formed that is stable (redox stable, thermodynamically stable, and dimensionally stable) and compatible (thermal expansion compatible and chemically non-reactive during operation and fabrication) with the electrolyte material. The backbone can provide ionic and/or electronic conductivity (if ionic, then usually the backbone is made of the same material as the electrolyte material and they are sintered together). Then the backbone structure can be coated with the electrochemically active phase (and also provide ionic and/or electronic conductivity if the backbone does not provide one). The coating can be formed by infiltrating a solution of nitrate precursors of the desired phase into the pre-sintered backbone structure and heat-treating at lower temperature than is needed to fully sinter a structurally-sound electrode. The backbone structure provides the structural stability. In prior work, such coating-type negative-electrodes have been comprised of: an interconnected network of Cu metal with dispersed doped ceria particles on a YSZ scaffold [7], an interconnected network of Ni metal particles on a YSZ scaffold [13, 14], interconnected network of chromate or titanate ceramics with low electronic conductivity on a YSZ scaffold [15, 16], and an interconnected network of doped ceria with dispersed Ni particles on an electron conducting backbone made of Nb-doped strontium titanate [9, 10] or FeCr [11]. An illustration of these type of coated backbone structures is shown in Figure 6-1. With this type of electrode, the active material does not need to be redox stable, dimensionally stable, thermal expansion compatible with the electrolyte, or chemically compatible with the electrolyte at the high sintering temperatures that would normally be required for fabrication. It only needs to be chemically compatible with the backbone material during operation and thermodynamically stable during operation.PDF Image | Electrolysis of CO2 and H2O

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
