They have little or no moving parts in the power plants. IE they are very very quiet and still very dangerous to surface shipping.
The fuel cells still need diesel engines (or other power source) to get the energy to split H from H2O to charge the cells

Fuel cells are more like super batteries for low speed operations. Batteries are still useful for high speed operations since they can dump a lot of charge to the E Motors quickly.
