Electrolysis, the passing of electric current through water will separate the water into oxygen and hydrogen molecules.
Electrolysis is used to separate sodium metal from table salt. It is easier to harvest hydrogen from fossil fuels, than it is to separate hydrogen from oxygen using electroysis of water.
Today - no. But they are working on it. If they can find a way to efficiently separate the hydrogen from the oxygen you can run a vehicle on the hydrogen.
This is the trick known as photosynthesis, where the oxygen is split from the hydrogen and expelled as a waste gas. The hydrogen is available and used by the plant to build its tissues.
Water is H2O. 2 hydrogen atoms and 1 oxygen atom. Water is not formed when you mix hydrogen and oxygen. An explosive mixture of hydrogen and oxygen is formed. When you burn hydrogen in oxygen, the resulting compound is water. When you boil water the result is steam, or water vapor. Boiling does NOT separate the hydrogen and oxygen. An electrical current is needed to separate the hydrogen and oxygen. CAUTION: Do NOT put salt in the water to speed up the electrolysis of water. It changes the products. instead of hydrogen and oxygen, you get hydrogen, chlorine (gas), and sodium hydroxide. The last two are very poisonous.
Used to have to do this by cooling (liquidifacation), by now they've got semi-permeable membranes that can do the job.
yes
There are different types of equipment used to separate water into hydrogen and oxygen, but the most common, in my experience, is the "Hoffman Electrolysis Apparatus".

Use a distillation column. It cools down the gases to below the boiling point of oxygen at high preassure. Oxygen condenses and forms a liquid that can be tapped from the column while hydrogen remains a gas. Why not separate the electrodes used in the electrolyzation process and trap hydrogen at one and the oxygen at the other? It is a lot easier, and probably a lot less dangerous (as a hydrogen and oxygen gas mixture is explosive).
Electrolysis can be used to separate H2O into hydrogen and oxygen.
separate the hydrogen and oxygen
In electrolysis, oxygen and hydrogen gas are produced at different electrodes (oxygen at the anode and hydrogen at the cathode). Since these electrodes do not have to be in close proximity, the hydrogen and oxygen will bubble upwards into separate collection vessels. If you needed to separate hydrogen and oxygen once mixed, the easiest way I can think of would be to cool the mixture to ~60K. At this point the oxygen would condense and leave hydrogen gas.
you do this and that and this and also that you do this and that and this and also thatYou can separate water into oxygen and hydrogen by the process of electrolysis.

electrolyzing water
They are working on that. They have machines that can separate the hydrogen from the oxygen. An automobile can run on hydrogen.
