membranes that were treated with the plasma; this was attributed to the poor contact between the electrode and the pressed Membrane Electrode Assembly (MEA) (Jung, et al., 2007). Another way of modifying the electrolyte is using a chemically altered electrolyte. Wang, Wainright, Savinell, and Litt tested a new polymer electrolyte membrane made from acid- doped polybenzimidazoles. They tested this membrane, which is chemically different from Nafion, using a DMFC. The polybenzimidazoles was found to increase performance by decreasing methanol fuel crossover (Wang, Wainright, Savinell, & Litt, 1996). Another type of membrane that has been tested is Poly(perfluorosulfonate acid) that has been doped with cesium ions and hydrogen ions. This membrane was also tested in a DMFC and was demonstrated to decrease the methanol crossover thus increasing the power (Tricoli, 1998). A study by Lehamni, Durand-Vidal, and Turq investigated the surface effects of the Nafion swelling. They used an AFM to measure the surface of the Nafion membrane after being exposed to either nothing (dry), water, or tributylphosphate. The AFM was in the tapping mode for the measurements to reduce the amount of force on the surface of the Nafion. This study did not complete a fuel cell test with the Nafion. The purpose of this experiment gain knowledge about methods of measuring Nafion using the AFM to measure Nafion and characterize the surface roughness parameters (Lehmani, Durand-Vidal, & Turq, 1998). Approach As one can see, the polymer membrane electrolyte has been studied quite extensively. This study will use an industry standard membrane Nafion, specifically Nafion 115. This will keep the starting width constant throughout the experiments. The Nafion membrane will be modified using a hot pressing technique to transfer a structure on the aluminum mold. Measurements of the surface of the Nafion will be taken by the Olympus LEXT3100 scanning 9PDF Image | surface roughness of the Nafion membrane in a PEM fuel cell

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
