Pure hydrogen doesn't burn, it needs oxygen. The Hindenburg disaster was so spectacular because the ship was made out of highly flammable canvas and wood. The hydrogen itself burned up very quickly once escaping. If the ship had been made out of metal it would've sprouted a brief jet of flame, then crunched to the ground in a fairly ungraceful manner, but it wouldn't have exploded. Maybe a graphene hydrogen containment cell could work? That would be strong enough to deal with the pressure, plus provide a flame resistant barrier.
