Title: Hydrogen/Chloriтe fuel cell
Post by: vdblnkr34 on 11/02/2022 16:20:27
Is it possible?

Hydrogen fuel cells create electricity combining hydrogen and oxygen together. Same thing do hydrogen/chlorine gas. Than what materials will be needed to make this reaction happen.

You could certainly make a Cl2 H2 fuel cell
What on Earth would be the point?
Are you looking for the most expensive fuel/ oxidiser pair?

Easier to get hydrogen form salt water instead of distilled water. Hydrogen/chlorine fuel cell would provide with more current and chlorine easier to deal with, while hydrogen/oxygen fuel cells you need generator as an extra or carry gases with you.

Why would it cost a lot of money for catalyzers? Simple liquid hydrogen/chlorine battery not hard to make and electrodes are made of a carbon.

But with hydrogen sulfide would work better than chlorine.

Be careful with your storage tanks and exhaust pipes:
- Cl2 as an oxidiser is toxic (it was used as a poison gas in World War 1)
- HCl as an exhaust gas is toxic (it is an acid, so it tends to corrode metals)
- H2S as an exhaust gas is toxic (and it tends to corrode copper conductors)
- Are you trying to compete with the toxicity of CO and NOx from conventional hydrocarbon fuels?

At least O2 as an oxidiser and H2O as a waste product are not toxic.

If you think that chlorine is easier to deal with than air...
What are you doing on a science page?

Electrolysers don't usually use either, they often use NaOH solution but... So what?

No.
