Electrochemical Reduction of Nitrostyrenes
uemura:
Hi Antoncho,
your idea for preparing a membran this way is new to Uemura. He thinks however to make it work (thickness, mounting, etc.) needs a lot of experimentation.
Uemura found in the meantime an hopefully appropiate device for the inner container. It is an unglazed growing pot for orchids. The anode he is going to construct will not be cooled from the outside, but from the inside. Ha! a very clever idea if it works.

foxy2:
What are your thoughts on a power source??
Will a conventional automotive battery charger work?
Will it generate too much power?
Is a 2amp load way too much?
uemura:
uemura has around a dc variable power supply (these thingies you can buy in electronic shops). The one uemura has allows adjustements for voltage and/or current. Costs should be about 50$ or so.
the electrochmical projects has seezed at the moment due to real-world overload. Hope to activate it end of the year.
Osmium:

They deliver more than 12V, and any excess current is converted into heat in the electrolysis cell which has to be removed by cooling. This is bad. At least use an old computer power supply (which delivers quite a lot of amperage). Or a regulated power supply. This allows for fine tuning, like current density etc.
> Is a 2amp load way too much?
In most refs no voltage is named, only the amount of Ampères, Faradays or current density. That's the reason why: current is regulated by the resistance of the electrolysis solution and the membrane, and the distance and size of the electrodes. So that question doesn't make much sense. By varying those parameters you can tweak a less-than prefect power supply into something that works, but it's always better to have a real regulatable power supply.
Unobtainium:
You might want to double check that power supply you found. I don't think one costing $50 (new) would be very suitable. A decent regulated variable supply should cost several hundred dollars.
