The working electrode sample should be coated on single side or double side on a current collector plate?
The working electrode sample should be coated on single side on current collector plates by keeping area of 1 cm x 1 cm with controlled and uniform thickness.
1. What do you want to coat it with? An insulating coating or a metallic coating?
2. If it is a masking agent ( insulating) you can use microstop lacquer or Dymax UV curable coating. It cures in 30 sec to 1min.
3.If it is a metallic coating- what is it you want to coat.
Thank you Mr.Madagonda Vadiya sir for your answer. I am having a doubt on why do we have to coat on the single side only?
You need to have a well defined area for studying the reaction rate etc. By coating on one side with an insulating coating like a "Microstop" lacquer you are restricting the reaction to take place on one side only which is what you want. If you have two counter electrodes and you are prepared to take the area on both sides you don't have to coat with an insulating coating. Even here your current collector lead etc have to be coated to be accurate with respect to the area and also to have reproducible area every run.
Dear Saranya,
Generally, The Unit area (1 cm) is used for the calculation of electrode performance. therefore, it is essential to coat single side (1 cm)
