Interesting project! I will have to give it a look.
sourcing the materials can be a bit of a challenge
Any more details here? I’m guessing the necessary material for electrolytic and what not? Do you know about the boring adjacent stuff like measuring (eg how accurate do the measurements need to be, how precise, etc), disposal, etc?

You need Polypropylen filament for printing, graphite felt as electrode, grafoil gasket material as bipolar plate, brass plate as current collector (cut by cnc), silicone gasket material and a measurment device like a potentiostat.

Why brass and why a thick plate of it? I’ve designed and built RFBs; we played with aluminum ‘sticker’ sheets on some rigid backing and it worked fine.

I’m not the designer of this. I’ve also wondered. Maybe it’s just a practical choice to have something tough to attach your wires to.
