Nope, because you don't make hydrogen tanks out of materials that are susceptible to hydrogen embrittlement.

In particular, pressurized automotive-size hydrogen tanks aren't made from metal at all, they are typically epoxy/kevlar/carbon fiber composites.

OOC, since you know what these tanks are made out of, what is the duty cycle/lifespan of those tanks? I was presented some info on Kevlar tanks for drones using fuel cells and remember thinking that the lifespan was very short.

Toyota certify and guarantee their tanks for 15 years, in production cars that you can go out and buy today.

Anything bound by epoxy (or any polymer?) surely will have a comparably short lifespan...
