Hydrogen is not an efficient conductor of electricity under normal conditions, but can be made to conduct well at a low temperature under very high pressure.

zero as the element +1 as the hydrogen ion -1 as the hydride ion
Electrical gadgets often contain hydrogen- not in the electrical components themselves but in the plastics used for example in insulators and structural components. The electrical components contain conducting meterials such a s metals and for elctronic devices semiconductors.
No, attempting to do so would be neither legal nor safe.
If you think to electrical charge the hydrogen ion (H+) is a cation. In water other species as (H3O)+ can exist.
I believe that would be a Hydrogen Bond.
Yes.
You need to electrolyse it. Hydrogen will be produced at the cathode.
Hydrogen fuel cells and solar photovoltaic arrays.
Both. This is synonymous to asking "Is hydrogen an atom or a molecule?"
The anion (HCO3) has the electrical charge -1.
Hydrogen can, especially in the case of electrical hydrogen production as the process creates it's own oxygen
