How we can calculate amount of ampere that we can take from different Electrochemical Cell?Sure it depend to dimension of cathode and anode and also
depend to Type of Electrolyte.I am trying to find formula for it.
For example How much ampere we can take from Copper/Zinc System with 20% acetic acid solution(Zinc/Copper dimension :2x7cm)The voltage of this
Electrochemical Cell will be 1.1

It also depends on the rate of diffusion of the ions to the electrodes, so you will have to take the mobility of these ions and the thickness of the
diffusion layer around the electrode into account.
Look up amperometry. This is an analytical method in which the current at various voltages is measured to determine the concentration of a compound.
The theory behind it explains a lot of the things that go into calculating this current.
However, at best you can only approximate it and 'the' formula you seek is not simple.
