How do you create energy using [ hydrogen fuel cells ]?

How do you create energy using [ hydrogen fuel cells ]? Topic: How to do a research project grade 5

Question: 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

Your teacher is right. You can split Hydrogen and Oxygen in water. You need: Some common things like a popsicle stick or two, distilled water, a lantern battery (which you should be able to find at a hardware store or hypermarket like Wal-Mart; if you can't, a 9 volt battery should work too) and 2 tablespoons of salt. Some not so common things such as a beaker (a pyrex measuring cup works just as well), 4 wires with alligator clips at each end and a volt meter (both of which can be found at your local radioshack), and a strip of copper and a strip of zinc. I imagine that your teacher should be able to scrounge these up for you but if they can't you can try using graphite rods from mechanical pencils. **You should always have someone (parent, older sibling) to help you perform home experimentation. You will be making gas that is flammable and dangerous in LARGE quantities.** 1. Fill the beaker with about 300 mL of distilled water. 2. Add the table salt to the water and mix well. 3. Attach the alligator clips to the anode and cathode. (Copper is your anode and should connect to the red aligator clip. Zinc is your cathode and connects to the black one.) 4. Suspend the anode and cathode in the solution but make sure they don't touch or it won't work properly. (Its been a while since I've done this. I'm not sure if they are allowed to touch the bottom of the glass or not.) To suspend the anode and cathode I recommend resting a popsicle stick across the mouth of your beaker and resting your electrodes on it (this means that the clips have to be at a right angle to the electrode). 5. Connect the other end of the the wires to your voltmeter to show that your salty solution doesn't have a voltage (or potential difference). 6. Disconnect from the volt meter and connect the anode (positive, red) and the cathode (negative, black) to your battery. If you look real close at your anode and cathode, you should see bubbles forming. Chlorine gas is forming on the anode (copper, red) and Hydrogen is forming on the cathode (zinc, black). 7. Disconnect from the battery and hook back up to the voltmeter. You should get around a volt or so (actually 1.4 V and decreasing). And you should see the bubbles slowly disappear. They aren't being absorbed by the rods but rather by the solution. A neat thing to do is check the pH of the water before you add salt, fter you add salt and after you disconnect from the battery but before you hook up to the volt meter. The process of applying electricty to water and producing Hydrogen and oxygen is known as electrolysis. I'll let you go do the research on that. It is a very neat process and is very inefficient as you can see by applying at least 9V and getting out 1.4V The process is also quite costly do to the type of electrodes used on a large scale. When you took the battry out of the circuit and hook it up to the voltmeter, you basically made an Alkaline fuel cell (again, up to you to do more research here). But fuel cells are pretty neat too. Once you have the fuel, a fuel cell is very efficient and noiseless because its just a chemical reaction. But they too are costly because of the electrode material. Hope you enjoyed your bit of science and good luck! ***DISCLAIMER: The author is not responsible for the unlikely event of injury or damage to those trying this experiment.

because switching cars from gasoline to hydrogen is a long way away. Yes they have cars that do run on hydrogen but do you not realize that the entire country would have to restructure every gas station to be able to have a ample fuel supply for the bulk of the country. Do you not realize just how much hydrogen that would take? Where would it all be stored? Also you can not forget the billions of dollars that it would require to be done. Also Hydrogen is much more volatile that gasoline so most gas stations would go back to full service because they would not trust the general public not to blow up there store. When it come down to it at this point in time it would be more economically feasible to focus on cutting the country's fuel costs through more economical cars. The bad part is most people in america do not want to drive economy cars they want cars that ride nice and have power. If people really wanted economy cars then the entire country would be driving Geo Metro's instead of Lincoln Navigators. Some day we will all be driving around in either electric or hydrogen powered cars but that day is not tomorow. Myself i am saving up to buy a Tesla which is the only cool electric car avalable at this point in time. I only have $175,000.00 to go.

Energy Secretary Steven Chu said the government prefers to target more immediate energy-saving solutions. "The probability of deploying hydrogen fuel cell vehicles in the next 10 to 20 years is low," Energy Department spokesman Tom Welch said in an interview.

Do you know how to obtain low-voltage electricity and work safely with it? If not, don't try what I'm about to describe. It's easy enough to make hydrogen and oxygen using electrolysis. Stick an anode and cathode in water, and apply low-voltage electricity. Hydrogen bubbles out from one side, oxygen from the other. However... it's much harder to turn the hydrogen and oxygen back into electricity! I can't imagine your teacher expects you to crack it, no offense! On the other hand, if you want to make the simplest possible battery, here's a very interesting article that was written for students. Start on page 11. http://books.google.com/books?id=IKIgAAA...

That is a good question and Many resreachers are working on this topic, the idea of this is simple but in fact it is very hard to generate H and turn back into electricity, you need to log in to science direct and read some artilces

that is a substantial load on the two remaining cylinders. it might run really rough and it might not run at all. the two remaining cylinders would be getting more fuel given that the rest of the engine i dead. the cpu would do that to maintain motion.
