When sodium hydride is electrolysed, in which electrode is hydrogen gas liberated in?

An electrode is a solid electric conductor that carries electric current into non-metallic solids, or liquids, or gases, or plasmas, or vacuums. Electrodes are typically good electric conductors, but they need not be metals. Cathode and Anode.

Electrodes and electrode materials are metals and other substances used as the makeup of electrical components. They are used to make contact with a nonmetallic part of a circuit, and are the materials in a system through which an electrical current is transferred.

When sodium hydride is electrolysed, NaH(s) will decompose before it is converted into Na(l) (unless the pressure is very low?). However, the response above is better than mine because not only did s/he acknowledge this fact, but supplied some useful data to show what WOULD occur if NaH(l) were in fact stable.
