Q:If fuel cell cars started using natural gas what would happen?

Natural gasno Propane yes, this could be used but is cost inhibitive. Few could afford it.

Q:compressed airhhoelectricalgaeethanolgaspropanefuel cellswhat else is there ?

compressed air the most inefficient engine ever invented, NO hho The compund HHO doesn't exist, so NO electric, where will the electricity come from? algae Maybe ethanol A very inefficient fuel to make, NO gas Natural gas has limits to, but a good choice. propane This comes from natural gas, it is an extension of natural gas. fuel cells, very inefficient, NO

Q:I came across a diagram where there is a picture of a car with a fuel cell and with it is a battery, what is the battery used for? To initially start the car?

Most fuel cells do require energy to start the reaction - but it is just initially to generate some heat. You could do this with a small battery to start it up, so the large batteries are not necessary for that. What they are there for is because fuel cells are good at providing a very consistent amount of electricity - they aren't very good at providing big bursts of electricity all at once, and you can't use regenerative breaking to recharge a fuel cell. So instead, you have a battery pack that is much smaller than the battery pack that would be used on a car like the Leaf, and instead you have a fairly small battery pack like the one used in a Prius or some other hybrid car. Personally, while I certainly like hydrogen fuel better than gasoline, it is ultimately just a stop gap until we can drive pure electric vehicles. Because of that, and because fuel cell technology is very expensive, and because we have ZERO hydrogen infrastructure, I'm going to skip them and get an all electric (Leaf) instead. :)

Q:I might repeat this question again later on with more info. But right now I just curiously want a real good opinion.Is a fuel cell vehicle really a good replacement for a gas vehicle?Easy 10 Points.

In an immediate pollution sense - yes. In an energy return sense - no. In an car enthusiast sense - I have no idea, probably not. In a price sense - definitely not. In a renewable sense - not quite yet, producing hydrogen is still inefficient. Either way it's nowhere near close to ready technologically for everyday use. Maybe in the future.

Q:And what is the fuel tank/cell made out of

I dunno wat that guys problem is CHUCK but the fuel cell is made out of sheet aluminium with a rubber safety bladder and safety foam inside. It's placed up between the frame rails inside a steel frame at the rear of the car ( in the trunk basically ) It holds 22 gallons.

Q:I am writing a research paper on fuel cells(hydrogen or any PEM fuel cell). I read in many of my sources that the government has invested millions, if not billions, into this research. They also state that there are specific goals that are suppose to be achieved by certain dates. I assume the goals include specific requirements on safety and efficiency of the fuel cell but I cannot find this information. Any information would be greatly appreciated and it must be from legitimate sources, Thanks to all who help.

Q:Fuel cells employ membranes to keep the fuel and oxidant separate from the anode and cathode. What happens when there is mixing between the fuel and the oxidant?

It depends on the nature of the fuel and oxidant. If they react spontaneously, you'd get combustion inside the the fuel cell, typically generating a lot of heat and causing the cell to burst or even explode. If they don't react spontaneously, they will just mix, causing the cell potential in the two half cells to equalize and rendering the cell incapable of producing electricity.

Q:I am trying to get the plans fora HHO generator.Preferably a .pdf fileor something like that.Also, if you have ever used this sortof fuel cell, let me know what youthink of it.

the FTC has confiscated hundreds of plans ask them. Make sure you tell them its for a news article, manufacturing and sale of these fraudulent systems are punishable. HHO doesn't exist, IUPAC is the world organization the names all chemicals, they have never heard of HHO. A H2 fuel cell combines H2 gas with O2 to make electricity. They are very complicated and require thousands of dollars of platinium.

Q:I previously posted a question on can cars be converted to fun from gasoline to hydrogen fuel cell. many of you said yes but i still dont know how it can be converted and exactly how much will it cost? thanks a bunch!
