Open the CIPO recordAbstract From the Canadian patent
A fuel processing system (fig. 27) is disclosed. The system includes a steam reformer (12) adapted to produce hydrogen from a feedstock consisting of water and at least one of an alcohol and a hydrocarbon feedstock. The hydrogen is produced by reacting the feedstock in the present of a reforming catalyst (102). The product stream is passed through a hydrogen-selective membrane module (54), at which the permeate stream is polished to remove trade carbon monoxide and carbon dioxide, and the byproduct stream is combusted to heat the reformer.

Why it's free to use
- Filed April 14, 1999 and granted April 1, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 14, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 14, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
