Hydrogen in fuel cells powers automobiles by A. generating electricity. B. creating rapidly combustible hydrogen compounds. C. generating changes in gas pressures that move pistons in car engines.D. combining with equal parts of gasoline to create a fuel with extra octane.
- In Who Killed the Electric Car, they mentioned several points against fuel cells. 1. The infrastructure is yet to be implemented, While you could theoretically plug an electric car anywhere, you'd be hard pressed to find an hydrogen cell at your 7-11. 2. They fail in cold weather. 3. They would cost $1,000,000 apiece while an electric car would cost $30,000 to $100,000 apiece. 4. The technology won't be feasible for another 15 to 30 years. It seems the oil hungry Republicans are excited about fuel cells because they are so unrealistic and far-fetched that they pose no danger to the status quo, unlike electric automobiles. Plus they can pay lip service to constituents by saying they're all about the environment.s
I have a buick lucerne that i love and will have it paid for in a couple of years. Do you think that we will ever be able to convert the cars that we now own to be e85 compatible, or even go as far as fuel cells?
- E85 has to be about a buck a gallon less for me to buy it. It gets poor mileage. There are too many cars out their that can burn E85 to convert one. Fuel cells are at this time a pipe dream.s
Help pleaseSomeday, cars may be powered by clean H2/O2 fuel cells and electric motors. Under standard conditions, such a fuel cell can develop 1.229 volts. If the oxygen is obtained from air (at P0.21 bar), what pressure of H2 would be required to develop 1.214 volts from the cell at 25 C?
- This is actually electrochemistry, and is a pretty weird question. First use the Nernst equation. EcellE*cell-0.0592/n*logQ; after plugging in the numbers you have listed above and using 4 as n (the number of electrons), you get: 1.2141.229-0.0148*log(1/x^2*0.21); you may want to check your numbers and reverse the Ecell values to get a positive result. From this point, just solve for x.s
I know Fuel Cells aren't designed to swap icons, but I've read a lot of feeds that say you can remove the icon if you desire. Just wondering if I do take out the icon if the Icon Packs made for the Batwolf or Dispatch would fit.
- no. They're all different sizes. Batwolf Icons are HUGE.s
I recently bought a pair of Oakley Fuel Cell from Zappos. I would think they're real and stuff but after reading about fake ones, I'm starting to second guess my glasses. On the right side of the frame I'm missing the Made in USA. All I have is the CE and as far as the left side of the frame I have the serial number ect. and I do have o (letter/logo) with the serial. So for all the Oakley's fanatics please feel me in, are they real or not? THANKS!
- Authentic oakley sunglasses are always so expensive for me to buy that I only can buy the cheap ones.And there is a good site that my friends and I have bought several pairs last month.The sunglasses are high replica but also of high quality,it is worth to buy.You can just try it,good luck!s
I find aluminum over NaOH is the easiest way to produce hydrogen (600 g Al can yield 70g1litre liquid h2)
- Maybe okorders
I have to somehow create energy using hydrogen fuel cells.This is for a grade 9 science project.My teacher said there is a really simple way by charging electricity into a container of water, and something about Electrolysis.Any ideas?Thanks
- Do okorders
First off, my intent here is not to find someone to do my homework for me. I'm in a graduate level engineering course and at a loss for how to start this problem.We're asked to calculate the hydrogen consumption for a fuel cell (hydrogen oxidized at the anode and oxygen reduced at the cathode). Information given in the text of the problem is the cell potential a (0.7 W) and power for the cell stack (1 kW).Ideas on how to start this thing are greatly appreciated!
- Go to wikipedia and look up standard electrode potentials for hydrogen half-reaction and oxygen half-reactions
