Hydrogen generator: Purer hydrogen, cheaper than bottled gas. Example, if you use 1.5 slpm of bottled gas, that's 15 cylinders/month (135 cf size). This is inconvenient and costs about ~$3,000/month. The alternative is this Me100-2 using 15 gal/month of metahnol-water (~$150) and 70kWh of electicity ...

We off a system to measure the permeation rate for gases through sheets of poymers or metal. The system meets ASTM standards. It is a small volume chamber with a presure sensor good to 0.01 mTorr, a high vacuum valve and a cell that can hold up to 2 atm on the high pressure side and vacuum on the low pressure side. Add gas to one side, vaccum out the otehr side; bake it out because of degassing, ...

Pt-CeO or Pt-alumina catalysts that remove unwanted H2 by combining it with oxygen. This is best done in the presence of air but the CeO version also works in nitrogen or inert gases. Uncoated catalyst works at 20°C to 600°C. Teflon coated catalyst works to -5°C. This is often used aboard submarines where battery-hydrogen is a safety hazzard. See our essay on ...
