Hi Peter, That's a lot of pressure and temperatures to work with... Remember the pressure will increase significantly when heated. Every part of your container needs to be rated for whatever the final temp/pressure combination is, including tubing, valves, sealant, etc. I'd like to know how you plan to safely bring hydrogen at 2000psi to 500C and then back down to a vacuum (of indeterminate pressure) inside a glovebox.
But, yes, you can order a tank with a hydrogen regulator (300 psi) and have the bottle filled to 2000psi and go direct from the bottle to your device. (Of course, your welding shop can give you advice on this... which will be "don't do it--you'll kill yourself".) - Brad
