No need to worry; Hydrogen's exceptional permeability means the gas will diffuse through the jerry can, into the atmosphere; thus lowering its internal pressure.
We can make vessels which will contain increasingly high pressures; however their permeability is higher, vs. older materials. This is a central problem of hydrogen as a primary fuel... Better to burn it (or convert it into methane) where and when it is produced.
