Delta G for Standard Hydrogen Electrode reaction

I'm dealing with electrochemistry problems.
For the following reaction
2H
+
+ 2e
-
H
2
Eº= 0 V
Does it make sense to say
ΔGº = -2FEº = 0
Which would mean the reaction is in equilibrium?

Does it make sense to speak about equilibrium of a HALF cell reaction?

Not really, but given any another half reaction, what would a ΔG=0 mean in this context?

If you will combine two half reactions in such a way that the final E=0 (hence ΔG=0), then yes, you will have an equilibrium.
