4 Chapter 1 Alkaline fuels cells and liquid hydrogen • increases the viscosity of the electrolyte, limiting the diffusion rate; and • alters the surface tension o f the electrolyte which can result in electrolyte precipitation in the micropores of the electrode rendering it partly inactive. AFC's cannot even tolerate the 380ppm or so of CO2 in air. A calculation for the rate at which carbonation occurs is given by Piperopoulou and Bloomfield[17]. The noble metal electrocatalysts in acid media at low temperature are poisoned by CO. For PEM cells the use of reformed hydrocarbon fuel requires some method of removing CO to less than 20ppm[25]. External selective oxidation was used by Ballard to convert CO to CO2, The reformate is mixed with a small amount of air and then passed through a column packed with 0.5% Pt on alumina. This method has subsequently been adopted by other PEM researchers[26]. 1.2 Vehicular storage of hydrogen The three. usual ways of storing hydrogen on board a vehicle are: as a compressed gas, in metal hydrides, or as a liquid. A comparison of these three methods, and others, has been presented by DeLuchi[27]. Figure 1.1 shows the storage density for an amount of stored hydrogen equivalent in energy to 151 of petrol[28]. Liquid hydrogen (LH2) offers the lowest combined mass and volume. Figure 1.1 0 40 80 120 160 200 240 280 volume (1) Comparison of hydrogen storage options.

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
