One thing to note about electrolysis is that when you re-combine the H2 and O2 molecules, you get exactly the same amount of energy back that was put in, to crack the water molecules in the first place.
As they say in physics "there's no free lunch".
And that is the problem with on-board electrolysis machines. You can't get more energy out of the water than you put into it. So you're not gaining anything. And since the machines you're using to crack the water molecules, and then re-combine the Hydrogen with the Oxygen, are less than 100% efficient, there's actually a net loss of energy.
To get a net gain of energy (for the car, anyway), you need to electrolyze the water off-board (for example, at home), and then put the gas in the car. But this will still be a net loss of energy (in total). It's just that you're shifting the energy loss to someplace other than the car. While your gasoline bill might go down a bit, your electric bill will go up.
