If you electrolyse 1 gallon of water into hydrogen and then run the hydrogen through a fuel cell how much waste water will the fuel cell generate?
The fuel cell will generate about 1 gallon of waste water. The reaction of hydrogen combining with oxygen in the fuel cell produces water as a byproduct. Since the hydrogen generated from electrolyzing 1 gallon of water would similarly combine with oxygen in the fuel cell to produce water, the amount of waste water will be approximately equal to the original volume of water electrolyzed.

How many moles in a gallon of hydrogen?
210.3 moles of H2 are contained in one gallon of H2O
How much does 35 percent hydrogen peroxide weight per gallon?
Hydrogen peroxide has a density of about 1.2 grams per milliliter. To convert this to pounds per gallon, there are roughly 3.785 liters in a gallon (1 gallon = 3.785 liters) and 1 gram is about 0.00220462 pounds. Therefore, 35% hydrogen peroxide would weigh approximately 16.7 pounds per gallon.
How much does 50 percent hydrogen peroxide weigh per gallon?
Hydrogen peroxide has a density of about 1.2 kg/L. Therefore, 50% hydrogen peroxide by weight would weigh approximately 6.6 pounds per gallon.
How much does a gallon of liquid hydrogen weigh?
Deuterium oxide -- or "heavy water" -- is composed of water molecules formed by two deuterium atoms and one oxygen atom. Deuterium is a stable isotope of hydrogen containing one proton and one neutron in its nucleus. The more common hydrogen atom contains no neutrons in its nucleus. Heavy water is about 10 percent denser than regular water. Its specific gravity is 1.106. Since regular water weighs 8.34 pounds per gallon, a gallon of heavy water, therefore, weighs 9.22 pounds.
What is the current status of hydrogen fuel?
Hydrogen is currently not viable. There are many reasons for this. First of all, hydrogen is not naturally occuring, so we have to extract it from water. This is done by a process called electrolysis, which is just running an electric current through water. Hydrogen itself is not a source of energy, but in reality a carrier of energy. The hydrogen is combined with oxygen in the atmosphere, and the result is water vapor. In this process, an electrical current is created, thus running a electric motor. However, hydrogen is not practical because it simply does not pack the punch that current fossil fuels do. One can go much further on a gallon of gasoline than they can a gallon of hydrogen at STP(Standard Temperature and Atmospheric pressure). The process is simply not viable at this present time.
How much does hydrogen cost per gallon at the?
The cost of hydrogen per gallon can vary, but on average it ranges from $12 to $16 per gallon. This cost can fluctuate based on factors such as production methods, distribution infrastructure, and government subsidies.

What is the mpg of hydrogen?
The fuel efficiency of hydrogen vehicles is typically measured in miles per kilogram (mpgge - miles per gallon gasoline equivalent) instead of miles per gallon (mpg). On average, a hydrogen fuel cell vehicle can achieve around 60-70 mpgge, depending on the efficiency of the specific vehicle and driving conditions.
How much does 50 percent hydrogen peroxide weigh per gallon?

How much thermal energy can you get out of a gallon of gasoline?
Gasoline can generate roughly 20K BTU/lbm. There are 6 lbm per US gallon.
How much does hydrogen cost per gallon at the pump?
around $3.00 per gallon in California, even though there is only 20 gas stations over there! :-)
If I split a gallon of water by electrolosis how many cubic feet of Browns gas would I get from it?
The exact amount of Brown's gas produced will depend on the efficiency of the electrolysis process and the volume of hydrogen and oxygen gases that are generated. However, typically, one gallon of water (which is approximately 0.1337 cubic feet) can produce about 1800 gallons of Brown's gas at standard temperature and pressure.
How many miles per gallon do hydrogen cars get?
Hydrogen cars typically have a fuel efficiency equivalent to around 60-70 miles per gallon of gasoline. However, this can vary depending on the specific fuel cell technology and driving conditions.
How large is the hydrogen storage tank on the Honda Clarity FCX?
It holds 3.92 kg of hydrogen at 5,000 psi. One KG is virtually identical to a gallon of gasoline in energy, so it is EPA rated at 60 miles per kg, 61 miles per gallon.
How much water is produced while burning one gallon of gasoline?
Burning 1 gallon of gasoline produces 1.52 gallons of water. How this is calculated:1 gallon of gasoline weights 8.66lbs, of which 1.4 lbs is Hydrogen, as gasoline contains 16% Hydrogen and 84% carbon by weight.This assumes gasoline has the chemical formula of C8H18, the same as Octane.Water is 11% Hydrogen and 89% Oxygen by weight. One gallon of water weights 8.35lbs, and contains .92 lbs of Hydrogen, and 7.43 lbs of oxygen.Therefore since hydrogen burned or in, equals hydrogen out after combustion, therefore 1.4 lbs of hydrogen burned, equals 1.4 lbs of hydrogen in the H20 or water created in combustion. By weight, 1.4 lbs of hydrogen divided by the weight of .92 lbs of hydrogen in water, equals 1.52. So 1.4 lbs of hydrogen in 1 gallon of gasoline, is converted to more gallons of water because gasoline contains more hydrogen per gallon, then does water.
How many grams of nitrogen in one gallon of pure water?
None. Pure water has only hydrogen and oxygen.
