At low cell voltages and high current densities, a lot of gaseous carbon dioxide is synthesized. It, thus, occupies a much larger volume than the methanol solution in the feed channel [13]. Consequently, if too much carbon dioxide is produced, the solution is no longer in contact with the diffusion backing and is not effectively supplied to the catalytic layer thus resulting in a drop of current. In other words, the current is limited by mass transport. 3 2.5 2 1.5 1 0.5 0 0 0.2 0.4 0.6 0.8 1 1.2 Time (h) Figure 13: Current oscillations at fixed potential and anode feed flow rate of 1ccm (T = 80oC, Anode catalyst: 4mg/cm2 Pt/Ru black, Cathode catalyst: 4mg/cm2 black, Cathode O2 flow rate = 75sccm, Thumidifier = 25oC) According to this hypothesis, the erratic oscillations are related to limited anode catalytic layer methanol concentration. When the cell voltage is switched to a value around 0.3V or less, methanol supply to catalyst layer becomes limited and its concentration in the catalytic layer declines. Crossover declines at the same time. Thus, less CO2 is formed due to low current. Then it is removed from the feed channel and methanol again reaches the catalytic layer and the cell can again produce a high current. As the current starts to rise and more CO2 is produced, fresh methanol is again unable to reach the cathode.

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
