Dry Hydrogen Production I am building a set-up to produce a controlled flow of dry hydrogen. I'm aiming for around 99.5 percent purity.

Am I right in thinking a PEM cell and Deterite drying tube should be fine for this? Or will I need a condenser of some kind?

Any tips?
Using molecular sieves comes to my mind, they're easy to use and efficient. You can find some practical information about how this is done for example here http://www.klmtechgroup.com/PDF/Articles/articles/Molecular-Sieve-Applications.pdf
