Where to get Hydrothermal Fuel Cells?

[maestro]

So I've been reading up on the wiki, doing some research for a friend who wants to build an ocean base, and we've unlocked the Nautilon, but it requires Fuel Cells. OK, fine... so I look up where to get the recipe for the Fuel Cells and... wiki doesn't say. Thought maybe it was rewarded by the questline that gives you the Nautlion Bay, but according to wiki, no. Checked a few space stations, nope, not sold there.

I think I remember seeing it in a Manufacturing Plant, but I had other things to get at the time (Atlas Passes, Cobalt Mirror, etc).

Surely that can't be the ONLY way to get them?

you make them. when you got the nautilon in the mission you should've received the blueprint for it , too.
however, if you purchased the nautilon blueprint from the nexus then I don't think there is away; check it again for the fuel cells blueprint.

[Cannon Fodder]

I bought my Nautilon blueprint, and did NOT get the fuel blueprint. I also do not remember seeing one available for purchase.

However, when I got to the 'underwater' part of the main mission (where you will be given the Nautilon blueprint if you don't have it already), I was, at that point, also given the fuel blueprint.

It was a the very start of the 'underwater' part, when I had to go out and look for the missing crew members.

Okay, so you DO get the Blueprint from the quest?

Apparently Wiki forgot about THAT part. I was gonna say... thanks!

If you to into your Nuatilon inventory and attempt to make it it should show you what you need to make it with, should be the following items once' your planted your nautilon pad down so you can enter the nautilon.
Salt x40
Cyto-Phosphate x40
Carbon x40

two ways to get the blueprint. Do the quest with the 'dreams of the deep' line OR unlock it via factory overrides...which are....WAY easier

[maestro]

Eh, the blueprint doesn't show up because I didn't do the quest, and I've not unlocked with the factory yet (I was focusing on passes, and other more expensive stuff first).

I'll do the questline, I'm already more than halfway there.
