Finding Graphite Plates to Build a Fuel Cell

AI Thread Summary
Graphite plates are essential for building fuel cells, with prices varying based on size, thickness, quality, and supplier. An alternative to solid graphite plates is graphite foil, which consists of thin graphite sheets pressed together, making it easier to work with for those lacking specialized machining tools. While the price difference is unclear, graphite foil offers greater flexibility in handling. For sourcing, one recommended supplier is McMaster-Carr, specifically part number 95715K63 for graphite foil.

How much are graphite plates? I need them to build my fuel cell.
 
Chemistry news on Phys.org
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 don't 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?
 
Thanks a lot.
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
