Potentiostat and powersource in electrochemical cell

[LucidDreamer]

Hi,

Could someone please explain to me some terminology. Is a potentiostat considered a "power source" for an electrochemical cell (the cell is for the CO2 reduction reaction). An example of this type of cell can be seen here:

Basically I need to describe in a a document (in words) how a potentiostat and powersource would be configured into a 3 electrode cell. I'm looking for the words that will sound like an engineer wrote it. Thanks

Lordy, what a Wall-of-Text at that link! Yikes.

Anyway, no, it looks like a potentiostat is a consumer of energy, not a producer of energy...

I've read that.

don't really see how it consumes energy. If its purpose is to maintain a potential difference that wants to equilibrate to 0V eventually, doesn't that require energy.Not sure what's wrong with the link but its the cell diagram in this reference:

What do you think powers that differential amplifier in the middle of all of that?

 

[LucidDreamer]

No idea what that even is.

Thanks you've been tons of help.

Any one else care to provide a sentence or two that would describe how a power source is connected to the cell that I cited, instead of posting links to wikipedia pages. thanks

Hmm, you mean you want us to write your paper for you, instead of you actually doing the reading and research yourself?

The PF doesn't work that way, especially for schoolwork. Thread is closed.
