clear differentiation of the two surfaces. However when a statistical F-test (Fig.6) is applied to both of the measurements, it is evident that the two measurements are able to be distinguished at or below the micrometer scale as indicated by the circle. From the area-scale plot (Fig.5) of the two measurements of the two membrane, there is about a 13% increase in relative area from the Nafion membrane modified by mold G1 to the Nafion membrane modified by mold T3 looking at the smallest scales. If the reaction which occurs in the fuel cell is affected by an increase in area then fuel cell performance is expected to see about a 13% increase. Fuel Cell Tests Fuel cell testing was completed in two trials. The first trial was with MEA 1smooth and MEA 2rough. The second trial was with MEA 3smooth and MEA 4rough. The surfaces referred to as smooth were modified using the G1 mold, which was subjected to grinding using 1 μm grit. The surfaces referred to as smooth were modified using the T3 mold, which was turned with a high feedrate. The two trials differed in the preparation of the MEA. The first set of tests (MEA 1smooth and MEA 2rough) run on the fuel cell were run using MEAs prepared using the traditional procedure. The traditional procedure involved a hot pressing step, using a pressure of 2,000 lbs of force and 270°F of heat for the purpose of affixing the GDL to the catalyst. It was hypothesized that this step in the MEA preparation process could have eliminated the surface textures imparted on the Nafion membranes. The first two test results can be found in Fig. 7, under MEA 1smooth (modified by mold G1) and MEA 2rough (modified by mold T3). The same tests were carried out a second time using newly prepared MEAs, MEA 3smooth and MEA 4rough, which were prepared omitting the second hot pressing step. Instead of going to be hot pressed the membranes were removed of natural solvents in a 70°C oven for an hour.

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
