Evaluator Electrolyzer

The Evaluator electrolyzer test stations are tailored to the needs of automated cell and stack tests for the evaluation of high-pressure proton exchange membrane-, anion-exchange membrane and alkaline electrolyzers. For each product development stage from the basic cell research to examine catalysts, membranes, the gas diffusssion or the cell design in total, there is a suitable test station. The testing options include proof of concept valuation in regards to performance, efficency and durability, up to the prototype analysis for behavior under different and dynamic conditions. Thanks to the flexibility in the design, the test stations find their home at many use cases. They are installed at R&D institutes and universities, labs of electrolyzer manufacturers, test service providers and production lines for stacks. In addition, they are practical for all experience levels of users and complexity of the testing task. The Evaluator Electrolyzer-Series can be used for simple load cycle tests, electrical characterisations, such as polarisation curves, but also for more advanced procedures like impedance spectroscopy, hydrogen cross over evaluation, simulation of power supply fluctuations, life cycle testing and environmental simulations in combination with climate chambers and shakers. To make this variety of applications possible, all test stations are equipped with electrolyte recirculation loops at Anode & Cathode, electronic flow control, temperature and pressure control, nitrogen purge and a electronic power supply management.
