Optimum anode to cathode distance?

March 30, 2010

I have electrochemical cell for Pt deposition on membrane, the anode and cathode diameter is 2.8 cm, how can I find the optimum distance between anode and cathode? Is there any formula for calculate the optimum distance?

Hi, Kosar. What would constitute that optimum distance? You are asking for an answer to a question that unfortunately isn't fully formed. But two things to be considered are that the closer the anode to the cathode, the lower the voltage; that means energy savings. But the further from the anode to the cathode, the smaller the relative effect of small differences in anode to cathode spacing on the current density. Good luck.
