Effect of Pressure SOFCs, like PAFCs and MCFCs, show enhanced performance by increasing cell pressure. The following equation approximates the effect of pressure on cell performance at 1,000 °C: ∆ Vp (mV) = 59 log P2 (7-8) P1 where P1 and P2 are different cell pressures. The above correlation was based on the assumption that overpotentials are predominately affected by gas pressures and that these overpotentials decrease with increased pressure. Siemens Westinghouse, in conjunction with Ontario Hydro Technologies, tested air electrode supported (AES) cells at pressures up to 15 atmospheres on both hydrogen and natural gas (42). Figure 7-14 illustrates the performance at various pressures: Figure 7-14 Effect of Pressure on AES Cell Performance at 1,000 °C (2.2 cm diameter, 150 cm active length) Effect of Temperature The dependence of SOFC performance on temperature is illustrated in Figure 7-15 for a two-cell stack using air (low utilization) and a fuel of 67 percent H2/22 percent CO/11 percent H2O (low utilization). The sharp decrease in cell voltage as a function of current density at 800 °C is a manifestation of the high ohmic polarization (i.e., low ionic conductivity) of the solid electrolyte at this temperature. The ohmic polarization decreases as the operating temperature increases to 7-22PDF 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
