How to measure the LSV curve correctly ?

09 May 2024 0 9K Report

I am conducting research on water electrolysis. I have a question about LSV measurement

In the case of the paper, the part with a current density of 0 is measured, whereas in the case of the measurement data, the current density is not zero at the part with a potential of 0. Even for other measurements, a value with a current density of 0 could not be obtained. What is the problem?

In the case of the data we measure, it was difficult to obtain a flat graph near zero. For most of the data, a graph with a slope was obtained when magnified, even if it appeared flat to some extent.
