storage is not ok, however my setup will probably require a small amount of storage around 13 to 20 psi. it's no ok to store hydrogen in any form, the smallest piece of dabre from a shattered tank can kill you depending on where it hits you, the small explosion is like flying container part bullets.
i will tell you something very odd, i had a cell explode 6 feet away from my computer, the little snap cover you pop out to add a extra cdrw to, well that plastic cover "somehow blowed out of the computer."
if you are going to store hydrogen you should take the proper saftey steps.
Cover your cell with a blanket.
put a board between you and the cell.
if anyone other than you is around at all, do not test your wfc, it is your fault if you put someones i out and you should be the one to have to pay for it!
if compressed hydrogen is what we have to have, then safety measures can be took to make it safe on low pressure, if its a high pressure such as 5000psi, then it can be safe to, honda did it!
dont ever think it might not blow up, when you think this you loose an eye or life!!!!! SAFE TESTING EVERYONE.
