Keeping Hydrogen separate?

[JMBuilder]

Hydrogen is a diatomic molecule, meaning it will almost always bond with another Hydrogen atom. Is there any way to prevent it from doing so (besides bonding it with something other than itself)?

[metaphor]

Not really, monoatomic hydrogen is highly reactive.

You could have a magnetic field to trap protons (hydrogen atoms without their electrons) but not any significant amount of mass. Or you could heat hydrogen molecules to very high temperatures (over 5000K) to make them disassociate into atoms.

[Scotius]

Deep freezing works too.
