Finding Graphite Plates to Build a Fuel Cell

Click For Summary

Discussion Overview

The discussion revolves around sourcing graphite plates for building a fuel cell, including alternatives like graphite foil. Participants explore pricing, material properties, and sourcing options.

Discussion Character

  • Technical explanation, Homework-related

Main Points Raised

  • One participant inquires about the cost of graphite plates needed for a fuel cell.
  • Another participant explains that the price of graphite plates varies based on size, thickness, quality, and supplier, and shares their experience using graphite foil as an alternative.
  • The use of graphite foil is described as beneficial due to its ease of handling compared to solid graphite plates, especially when lacking the necessary tools for machining.
  • A specific source for graphite foil is provided, including a part number from a supplier.

Areas of Agreement / Disagreement

Participants generally agree on the variability of graphite plate prices and the potential of using graphite foil as an alternative, but no consensus is reached on the specific advantages or disadvantages of each material.

Contextual Notes

Limitations include the lack of detailed pricing information and potential variations in material properties that may affect performance in fuel cell applications.

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 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.
