Hydrogen Permeation Membranes
The core of our expertise, and where REB Research started out, was sandwich-type hydrogen permeation membranes. Metallic membranes are 100% selective to hydrogen and several metals are more permeable and lower cost than palladium. We have several patents in membranes and modual designs and we also recently got a grant in this area.

Hydrogen Purifiers
REB Research makes hydrogen purifiers and hydrogen purification modules that operate at 100 to 500 C, and 0 to 200 psi. Our Mr. Hydrogen, hydrogen purifier is a complete, easy to use unit that delivers ppb quality hydrogen gas for use in gas chromatographs and electronic manufacture. In these applications it saves approximately $400/cylinder compared to UHP-Zero grade hydrogen. We also sell the purifier modules alone, for OEM and specialized uses like isotope separations, and mobile hydrogen generation, e.g. by methanol-water reforming. Our purifiers and membranes resist fouling from water, methane, ethane, CO, CO2, and ppm levels of H2S. Because our membranes can operate at lower temperatures than traditional palladium-silver, they can pass fewer impurities: 1 to 40 ppb verses about 1 ppm for palladium silver. Hydrogen output vs temperature and pressure and for Flux vs time. For more about our membrane technology

Membrane Reactors
A significant focus of REB Research is membrane reactors, an exciting new technology used to generate ultrapure hydrogen from methanol, hydrocarbons, or ammonia. Such reactors are much more efficient and compact than any alternative of sequential reactors and separators. Click here for an essay on the advantages of membrane reactors for use with fuel cells.

Hydrogen Sorbers
As part of our sandwich membrane work, we started deveolping 2 types of hydrogen sorbers. Sandwich metallic and organo metallic. The latter involve fullerenes and work in air. We make the only line of non-flammable, non-carcinogenic (as best we know) hydrogen sorbers. Our metallic sorbers also have exceptional capabilities when used in metal hydride batteries.

Catalysts
We're not very expert at catalysts. Working with the Royal Military College we tried a lot that was available and found nothing that worked well at the temperatures and pressures of hydrogen reactors. Over the years, we developed a few that worked better than any on the market and continue to work with RMC to develop better stuff.

Hydrogen Transport Barriers
We have gained expertise coating gold and other low-permeation materials on stainless steel to reduce the rate of hydrogen transport.
