All the hydrogen will be stored in another chamber, once burned in combustion engine, (burning hydrogen leaves water) and walla! Exhaust will be water vapor and the leftover oxygen from the electrolisis.
I think burning hydrogen is something that manufactures will move away from since it is so inefficient (compared to hydrogen fuel cells). It takes a fair amount of power to create hydrogen from water, unless you add impurities such as salts which increase conductivity. But then you end up with waste products such as sodium, patassium ect.

Remeber you cannot create nor destory energy. So you need to take energy from somwehere to run the actual car. If you have a pump and perform electrolisis where are you getting the energy needed to do this?

I read the first post about using kenetic energy to propel cars. The only problem with that is again you cannot create nor destroy energy. With the fan on top of the car that creates electrical energy which in turn pushes the car forward, that system has a gain of grater than one, since the same wind which turns the fan, also pushes against the car. The car has mass and inertion, which changes due to road resistance.
