Surface or snorkel, fire up the diesels to run an electric generator to hydrolyze ocean water to H2 and O2, and charge the fuel cells.

Frankly, I'd be shocked if the sub were able to haul enough H2 and O2 to power the PEM for months at a time. Those would be absolutely massive fuel tanks.

When it comes to sheer energy density, it's hard to beat fossil fuels.
