Please be specific. Do you mean performing half reaction or MEA test? what kind of reaction?

Graziela Ferreira

Yes. Depending of your working conditions, you can see oscillatory behavior in the electric current.

This is because of the coupling between adsorption isotherm from 2 especies, at least.

You can see in some papers.
