H2 is valid fuel for combustion, is either H+ or OH- also valid?

[Schrödinger]

What do you mean H⁺ or OH^- ? What is the counter-ion in each case?
Cations or anions cannot exist in isolation

Doing an experiment atm, through H2O Hydrolysis we get those 2 ions, i suppose when in contact with the air we will have Nytrogen Hydroxyde and H2. I could be horribly mistaken though as I am really new to chemistry

A hydrogen atom is made up of 1 proton and 1 electron. Electrons have a negative charge, so when an atom loses an electron it becomes positive charge.
Since H+ is positive, we can figure out that it's lost it's electron, and all that's left over is a proton. Protons can't combust, so there's your answer.

Hydroxide ions can't combust either.

Doing an experiment atm, through H2O Hydrolysis we get those 2 ions (you may well do, but not in the gaseous state where they react with other compnents of air)

The gaseous components produced are H₂ and O₂
