Yes, AFAIU, this is one of the arguments favoring NH3 as a hydrogen energy store: the problem that H2 is such a slippery little bugger.

NH3 fuel cells may be tricky, but its a bottleneck: the difficulty in keeping H2 from leaking is an across the board challenge to fabrication and installation technology across the entire fuel supply chain.
