A self-starting, self-sustaining hydrogen generator comprises a reactor packed with a mass of mixed catalyst, containing supported copper and palladium. A feedstock, of e.g. methanol and an oxygen source such as air is injected at , high velocity into the mass of catalyst through a multipoint entry such as a tube of porous ceramic. The mass of catalyst is preferably configured concentrically around the tube injector so that the fluid-flow follows a , radial path through the reactor. The product gas is high in hydrogen and can be used as a feed for a fuel cell.

Why it's free to use
- Filed June 26, 1995 and granted August 19, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 26, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 26, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
