Where is the cheapest place to buy platinum mesh (for electrodes to make hydrogen in my electrolysis machine)?

Question

preferably a site or store i can order from

i dont want to spend anymore than $150 so if you know any other metals that make just as good electrodes please suggest them

Answer 1

Platinum is about the most expensive stuff you can use. If you are using a Nickle-Hydrogen cell, you may need it.

Gold is an excellent conductor and is fairly non-reactive. It is expensive, but cheaper than platinum.

Silver and copper are excellent conductors, but you should pick something that will not dissolve in whatever solution you are using.

Answer 2

Try zinc. That is what I used for the same experiment. You can find zinc pretty cheap.
