x = − b ± b2 − 4ac = − 0.8012 ± (0.8012)2 − 4(0.426)(0.0666) = - 0.0873 and - 1.794 2a The only root that is physically possible is x = -0.0873. The following table summarizes the effect of accounting for the water gas shift equilibrium: 2(0.426) mol percent FC outlet Gas w/o shift.

(b) Assuming a cell area of 1.00 m2 per cell and 280 cells per stack, how many stacks are needed for this 2.0 MW unit? Solution: (a) Recalling that power is the product of voltage and current, first determine the total current for the fuel cell as P ⎛2.0MW⎞⎛106 W⎞⎛1VA⎞⎛ 1kA ⎞ I = V = ⎜⎝ 0.600 V⎟⎠⎜⎝1 MW⎟⎠⎜⎝ 1 W ⎟⎠⎜⎝1000 A⎟⎠ = 3,333 kA Because each individual cell will operate at 400 mA/cm2, determine the total area as I ⎛ 3,333 kA ⎞⎛1000 mA⎞⎛1000 A⎞ 2 Area = Current Density = ⎜⎝ 400 mA / cm2 ⎟⎠⎜⎝ 1 A ⎟⎠⎜⎝ 1 kA ⎟⎠ = 8,333,333 cm b) The number of required cells and stacks are calculated simply as No. of Cells = No. of Stacks = 1 m2 per cell ⎜⎝ 10,000 cm2 ⎟⎠ = 833 cells () 8,333,333 cm2 2 ( )⎛1m⎞ (833 cells) = 2.98 stacks ≅ 3 stacks (280 cells per stack) 9-12PDF Image | Fuel Cell Handbook (Seventh Edition)

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
