DND has contributed R&D money to Ballard. For now, I believe the intention is run the boats as presently configured but in a later conversion, either replace the batteries with fuel cells, or augment them.
In these boats, the electric propulsion motors get their electricity from the batteries which are charged by running diesel engines either on the surface or at periscope depth (using the snorkel). Below periscope depth the endurance of the submarine is limited by the battery charge at the time of diving.
With fuel cells, electricity can be produced without the need to surface or use the snorkel(a submarine on the surface is vulnerable and snorkeling is noisy. This allows for greater undetected, submerged endurance below periscope depth. It is especially handy for under ice operations in our third ocean.
Hooray for our Navy and hooray for Ballard.
