Hi Josh

Yes hydrogen  is really volatile and explosive too when mix with air . It
diffuse true
material because it's the smaller atom, but diffuse less than helium
because it last orbit
is not full and it get bind to material by the electrostatic force.

Hydrogen it's the gas of choice for spark gap ( tyratron and Cie ) because
of it recovery
time ( quench really fast  ) and it's speed of heat transfer is the fastest.

In the past  many spark gap use alcohol or kerosene vapor, methane or city
gas because the
arc dissociate the molecule and after a short time you have a gap burning
in an atmosphere
riche in hydrogen. The poulsen system use this idea, check this link.

In the 1900-1920 time they built spark gap in Seri with city gas lamp,  the
spark gap is
inside a casing feed by gas and the hot gas feed the lamp.
