On page A49-fig. 8 of this article, "Analysis on cycle-life performance of ALB with three-electrode" has been done. When you measure the cycle-life performance of the "full cell" with 3 electrodes, what are the working and auxiliary electrodes? I know how to record just anode or cathode cycle life performance in a 3 electrode test setting, for example if you test the anode (working electrode), the cathode will be the counter electrode, and the reference will be 3rd. But can somebody define the electrodes in the full cell cycle-life performance test please?
The use of a reference electrode offers the possibility to seperately measure a half cell potential. In a full cell, it doesn't really matter what the WE and what the CE is. By substracting the measured half cell potential from the full cell voltage, you can calculate the second half cell potential.
Experimental hint: Most potentiostats or cyclers offer one current line and one sense line per channel. Obviously the current lines have to be connected to the anode and cathode. If you want to control the full cell voltage (like in your posted paper), you will have to connect the sense lines to your anode and cathode too. Though, to measure a half cell potential (any electrode vs. RE) you'll need a second pair of sense lines and therefore a second channel.
It was illustrated in Figure-1. So you need two channels for the experiment....
