Misleading and/or just plain wrong.

Why is it wrong?

If hydrogen is an energy source, where are the hydrogen wells/collection
facilities? Answer: there are none.
Hydrogen either must be obtained by breaking chemical bonds in oil
(therefore using oil), or breaking the chemical bonds in water (with,
for example, electrolysis). Breaking chemical bonds takes energy and
resources. There just isn't a bunch of hydrogen floating around for us
to extract - the hydrogen is all bonded to some other atom (bummer).

How much hyrogen is can be obtained from petroleum relative to the energy
required for fueld cells?

Or do you have a marvellous scheme for breaking the laws of
thermodynamics?

Do you have anything other than weaseling?
