Associated with the anodes are anode passages which in each cell are divided into a first group formed by anode passages (28a) and a second group formed by anode passages (28b). Fuel gas, for example methane from a supply (26) is fed via path (34) to an inlet manifold (38a) to the anode passages (28a) and a , portion of anode exhaust gas from the anode passages (28a) is fed via an exhaust outlet manifold (40a) and lines (42 46) to an inlet manifold (38b) , feeding the anode passages (28b).

Why it's free to use

  • Filed November 3, 1997 and granted January 28, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 3, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 3, 2019.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
