I think it would depend on what you plan to use it for.
Isn't it possible to buy tanks of hydrogen?
You can also look online for chemical reactions that produce hydrogen.

Well if you mean "the most" as the greatest volume of hydrogen gas per weight of reagent, you would need something that has a large percentage of hydrogen. Lithium hydride for example. All you have to do is heat it and collect the gas. A waste of lithium hydride though. Not very economical either. If you mean "the most" as in greatest volume of hydrogen gas for the cost to obtain it than I'd say build a space ship and siphon it out of the sun. There's currently about 1.35*10^30 kg of hydrogen available there. So, even if the space ship cost billions it would still be economical overall.

Applying an electrical current to water will split the H2O into hydrogen and oxygen gas.

Man, if you gotta ask, then you ain't qualified to handle hydrogen. You'll blow up your house and upset the cat.
