High current (DC and EIS) measurements on electrolyzers – Application Note 63Latest updated: May 6, 2020
Proton Exchange Membrane Water Electrolyzers (PEMWE) are used for hydrogen production with the purpose of storing excess electricity from renewable energy sources. This hydrogen can then be re-used to produce electricity for the grid again, for Power-to-Gas, or for hydrogen mobility (fuel cell cars, etc). This technology requires high current densities and power for efficient conversion ratio. In this application note, the connection of the cell to the instruments and the software settings are described. The resulting data of the measurements are briefly discussed.
