How much are graphite plates? I need them to build my fuel cell.
The price would of course depend on the size, thickness, [quality], and where you buy the plates.
As a substitute, when I build my fuel cell a little while back, I used "graphite foil" instead of graphite plates. What that is, is very thin graphite sheets that are pressed together under a lot of pressure to make a soft piece of graphite.
I dont remember if there was a price advantage to this, but it made working with it easier since I didnt have access to the tools I would have needed to machine the solid graphite plates, I instead used the much solfter "graphite foil", which I could peal away layers and work with easier.
Cool. Where do I get this stuff?
I got it from http://www.mcmaster.com/
