“Hydrogen thyratron typically utilizes titanium hydride in it’s reservoir and the hydrogen gas is released when the reservoir is heated and recombined into titanium hydride when the temperature cools down.” I’m guessing there’s an excess of H in the titanium hydride, so even if some of it leaks out, it’ll be able to maintain operating pressure.
