Dear All:

Our plastic hydrogen battery design requires the containment of hydrogen as well as water. I really would appreciate a brief summary of how Plastic A can be a better Hydrogen barrier than plastic B, but plastic B is a better water barrier than Plastic A. Furthermore, I am interested in long term mechanical retention due to the influence of - I suppose in this case - water in the polymer combined with temperature en compressive stress effects.

Thank you in advance for any help you may be able to provide.

Richard.
