Open the CIPO recordAbstract From the Canadian patent
In a PEM-type fuel cell, coolant conduits (79) are provided that follow the reactant gas flowpaths on either side of the MEA (70) and are formed in the interface between adjacent contacting separator layers (72) of consecutive fuel cells in the stack. These coolant conduits can eliminate the need for coolant conduits that pass in the stack dimension through the MEA layers.

Why it's free to use
- Filed July 1, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 1, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 1, 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.
