Figure 2-10 Conours of Current Density on Electrolyte Current density is shown on the electrolyte and air-flow velocity vectors are shown for the cap- end of the tubular fuel cell. Cathode and support tube layers have been removed for clarity. Results indicate that current density and fuel consumption vary significantly along the electrolyte surface as hydrogen fuel is consumed and current flows around the electrodes between interconnect regions. Peak temperature occurs about one-third of the axial distance along the tube from the cap end. NETL’s CFD research has demonstrated that CFD-based codes can provide detailed temperature and chemical species information needed to develop improved fuel cell designs. The output of the FLUENT-based fuel cell model has been ported to finite element-based stress analysis software to model thermal stresses in the porous and solid regions of the cell. In principle, this approach can be used for other types of fuel cells as well, as demonstrated by Arthur D. Little and NETL (16,18) Further enhancement of the design tool is continuing. The next steps are to validate the model with experimental data and then extend the model to stack module and stack analysis. NETL now operates SOFC test facilities to generate detailed model validation data using well- characterized SOFC test specimens. These steps should make it possible to create a model that accurately predicts the performance of cells and stacks so that critical design information, such as the distribution of cell and stack stresses, can be provided to the fuel cell design engineer. 2.7.5 1-DCellModels 1-D cell models are critical for constructing 3-D models, but they are also highly useful in interpreting and planning button cell experiments. In 1-D models, all of the critical phenomena in a cell are considered in a 1-D fashion. Generally they incorporate the following elements: 2-31PDF Image | Fuel Cell Handbook (Seventh Edition)

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
