Model in transparent plastic of a laboratory test cell for water electrolysis used to screen components. Reference electrodes are integrated on both the anode and cathode side to separately measure anodic and cathodic overpotentials.
Lifetime and performance investigations on cell components for PEM water electrolysis. A variety of electrochemical measurement techniques such as polarization curves, impedance spectroscopy, cyclic voltammetry, etc. are applied.
Screening of material and components in single cells with reference electrodes on the anode and cathode and in short stacks up to 80°C and 50 bar operating pressure.
Development of accelerated stress tests for PEM water electrolysis
Investigation of surface characteristics with ESEM / EDS
Structural analysis with 3D x-ray microcomputer tomography (microCT)
Analysis of water contaminates and corrosion products with ICP-MS
