Proceedings of the 2002 U.S. DOE Hydrogen Program Review NREL/CP-610-32405 cell stacks has operated for over 1200 hours with measured open-circuit voltages approaching theoretical EMF values for the particular hydrogen/steam ratio and cell temperature. Figure 3 shows data measured from the five-cell stack currently operating on 35% H2O/65% H2 at 925°C and 50 mA/cm2. The figure also includes a one-cell stack running cyclically at the same conditions. Leak testing of selected cells during operation detected minor seal leakages; however, the low differential gas pressure across seals led to minimal adverse effects. Differential shrinkage of seals versus electrodes is currently believed to be responsible for increased ASR. Future development work on seals is expected to produce improvements in both areas. 1.2 1.0 0.8 0.6 0.4 0.2 0.0 1.2 1.0 0.8 0.6 0.4 0.2 0.0 Electrolysis Voltage/cell (V) Voltage (V) 0 5 Cell Stack, 925oC, 35% Steam, 65% H2O 50 mA/cm2, FC only 500 1000 Time (hours) 1500 0 1 Cell Stack, 925oC, 35% Steam, 65% H2O 50 mA/cm2 200 400 600 800 Time (hours) Fuel Cell FIGURE 3. LONG TERM OPERATION IN FUEL CELL AND REVERSIBLE MODE. Engineering Studies A residential scale, grid independent application, using fuel cell and reversible fuel cell systems, was studied during Phase I. High-pressure, pure hydrogen and batteries were assumed as the energy storage mechanism. The small scale and low capacity factors for this contributed to the relatively high unit installed costs and a high cost of electricity. The reversible system projected round trip energy storage efficiency of 73% exceeds the 70% goal of the Hydrogen Program. The study also considered alternative approaches that de-emphasize the scale limitations in the residential application. The low capacity factor was a major challenge therefore alternate 6 Fuel CellPDF Image | Nafion Resins: Novel Device Applications

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
