Impedance measurements on fuel cells and fuel cell stacks at high currents: Part 2 – Autolab in combination with an electronic load

Main document

The use of impedance measurements on fuel cells under load makes it possible to study the influence of the different fuel cell elements on the behavior and (if detectable) on the ageing of the fuel cell. To perform high current density measurements, the Autolab systems can be connected to a third party electronic load. This extends the measurable range of the instrument by several current decades.
