Why does my water in my hydrogen fuel cell turn to a weird color?

When I turn on my hydrogen fuel cell or HHO fuel cell and it runs for a little bit, the water starts to turn like yellowish brownish. And it starts to form bubbles on the top of the water that turn really dark brown or black. What kind of water do I need to use and if I need to mix something in with the water, what is it?
Thanks Dave I didn't want to mention that i was using tap water because I wanted to see if someone would state that could be the problem, but when i use distilled water do I need to mix anything in with it. Or can I for better results?

Why do US major auto makers not implement hydrogen fuel cell cars across the country along with fuel stations?

Regular Americans cant afford Hydrogen fuel cell cars on their own and the only place that has it CA, they have every thing there. Well what about the rest of us. Regular Gas Mileage doesn't do crap its still polluting the earth and killing off the best natural resource known to man EVER hydrogen would solve so much pollution problems. Hydrogen has been proven save, yes it will cost billions of dollars but even in this so called recession the huge companies have billions if not trillions stocked away i mean really how many numbers do they need in their bank statements to feel like "rel men" WTF im happy with 20 bucks and something to eat. It is the only way its going to happen is if the govt and major car makers put up hydrogen fuel stations and sell them nation wide and hopefully world wide. Imagine the billions of metric tons of CO2 per year no longer in our air, the world is at an all time low of O2 content ever in recorded history. Just something to think about, and if any automakers happen to read this just imagine how insanely rich you would be if you are the first company to go nation wide with this hydrogen plan. Sounds like a winner to me 🙂

What is a good car for me to buy in the next couple years? Going to College soon!?

I want a car that is FUEL effect car, I'm s high schooler about to be in College soon.

MUST HAVES

-carbon fiber body (strong and cheap, like F1 cars) or other strong but cheap body.
-hydrogen fuel cell
– plug to recharge its battery
-can use biofuel
– AND ONLY IF NEEDED GAS

I was looking at the CHEVY VOLT, but i want to know some other cars that are similar, gas only gets like less than 20% of it stored energy.

BY THE WAY MUST BE CHEAP!

Air powered car??????????????

Why don’t the auto makers just make a car that runs off of pure oxygen? Wouldn’t it be cheaper to make a car that takes in air form outside. Separates the nitrogen and compresses the oxygen using that for the combustion instead of putting thousands of dollars in to hydrogen fuel cell technology and electric cars? all it would require are storage tanks and a highly efficient air compressor as well as a slightly modified engine.

where could i find a web site for a science fair project to build a battery powered cars for the science fair?

i need to make a battery powered car to test with a hydrogen fuel cell car for the science fair coming up on june 16th and i need the steps on building a battery powered car. i need a step by step process in building this car.

E85 fuel car (4 questions)?

1.Other than these marks, Chrysler, Ford, General Motors, Isuzu, Mazda, Mercedes, Mercury, Nissan, are any other comapanies such as Subaru planning to make e85?

2. How is e85 made. What is it made out of other than corn?

3.Are there any pros and cons about e85?

4.Like the hydrogen fuel cell car can i make home made e85? Can i make a mini car and test?

Why do people have a problem with Hybrid or Pure Electric vehicles?

I don't see why we can't see that sometime in the near future we as americans are going to have to find another source of fuel but it seems that to most Americans Gas is it and they don't see any other alternative.

Look people these Hydrogen fuel cell vehicles that the auto company's are showing you are a bunch of crap. Just as easy as you can make a Hydrogen Car you can develop an electric car because basically a hydrogen car is an electric car they just use hydrogen (FUEL) to make electricity instead of Batteries

Somebody had asked a question about what to do with hybrid batteries when we replace them. I don't know what do we do with the million plus Cell phone batteries and Laptop batteries that are all over the world ohh yeah we recyle them.You see the same batteries that power your laptop and you cell phone can power your car ohh and power your home through your electric vehicle if you have a VEHICLE TO GRID charging setup . You People need to wake up!
