The cell voltage starts to drop at the low current density region (above 50 mA/cm2), which indicates a loss in the activation regions. At the medium current density range where the ohmic resistivity region was (200-400 mA/cm2), the polarization curve of 1.0 wt% MEA starts to show a great loss than the 0.5 wt% MEA. This indicates that the 1.0 wt% MEA has a higher proton resistivity than the 0.5 wt% MEA. in Figure 4.7 the maximum power density of the 0.5 wt% and 1.0 wt% MEA were 92 mW/cm2 and 65.26 mW/cm2 respectively. It was expect to obtain higher power density due to the extra of inorganic filler in the MEA, but it was found that the power density was less than the 0.5 wt% MEA. The increase in the weight percentage of sulfonated mordenite into the membrane was expected to increase the power density of the fuel cell via improving the proton conductivity and reduce the methanol crossover. Increasing the weight % of sulfonated mordenite reduced the power density of the fuel cell. Introducing the sulfonated acid group on the surface of the mordenite increased the power density when using 0.5 wt%. From this aspect, the increment in the weight of SULFO-MOR was expected to ease the proton hopping across the membrane and reduce more methanol Sirhan AL-Batty Page 138 voltage (v) Power Density (mW/cm2)PDF Image | Membrane Electrode Assembly Modification by Zeolite and Graphene Oxide

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
