Characterization of Fuel Cells

We characterize cell components and membrane electrode assemblies (MEA) with regard to their performance and aging behavior as a function of the operating conditions. We use a variety of state-of-the-art electrochemical measurement methods. In-situ characterization provides deep insights into the physical-electrochemical processes of fuel cell degradation. We supplement this with extensive ex-situ analyses in order to examine the operating behavior of the components in relation to their microstructures and material composition.


We offer:

  • Fully automated characterization of MEAs and their individual layers using polarization characteristics, electrochemical impedance spectroscopy with air/H2 or N2/H2, cyclic voltammetry, linear sweep voltammetry, limiting current density, CO stripping and CO displacement
  • Spatially resolved characterization of local effects on customer-specific, segmented individual cells to check the cell design in full format or in an along-the-channel test cell, for material and component selection and for the development of operating strategies
  • Investigation of performance and aging behavior as a function of customer-specific designs and operating conditions
  • Investigation of the influence of contaminants on the anode or cathode
  • Ex-situ analysis of fuel cell components using scanning electron microscopy (SEM) and energy dispersive X-ray (EDX), micro-computed tomography (µCT), inductively coupled plasma-mass spectroscopy (ICP-MS), X-ray fluorescence analysis (XRF), laser profilometer, laser scanning microscopy, gas adsorption, porosimetry, corrosion current measurement, contact resistance measurement and more
