Open the CIPO recordAbstract From the Canadian patent
Multiple stacks of tubular electrochemical cells having a dense electrolyte disposed between an anode and a cathode preferably deposited as thin films arranged in parallel on stamped conductive interconnect sheets or ferrules. The stack allows one or more electrochemical cell to malfunction without disabling the entire stack. Stack efficiency is enhanced through simplified gas manifolding, gas recycling, reduced operating temperature and improved heat distribution.

Why it's free to use
- Filed May 7, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 7, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 7, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
