Open the CIPO recordAbstract From the Canadian patent
A fuel cell power plant and a method of operating a fuel cell power plant which allows indirect control of the reformer burner flame temperature are disclosed. A hydrocarbon fuel is reformed to provide a hydrogen rich fuel stream and the hydrogen rich fuel stream is oxidized in a fuel cell. A stream of anode exhaust and an oxidant stream comprising cathode exhaust and air are combusted in the reformer burner. The mass flow rate and composition of the oxidant stream are controlled to maintain the oxygen content of the burner exhaust within a predetermined range and thus maintain the flame temperature of the combustion mixture within a preferred range.

Why it's free to use
- Filed April 20, 1990 and granted August 21, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 20, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 20, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
