There are various types of water electrolysis test benches according to different classification standards, and the following are some common classifications:
Classified by electrolyte type:
Proton Exchange Membrane (PEM) Electrolysis Water Test Stand: Used for testing PEM electrolysis cells, it has the advantages of low DC power consumption, high current density, and small volume. The PE series PEM water electrolysis membrane electrode testing system developed by Beite Measurement and Control can be used to test the polarization curve and hydrogen production energy efficiency of electrolytic cells.
Alkaline electrolysis water test bench: suitable for electrolysis water testing of alkaline electrolytes, such as the PLS-MECF series dual chamber alkaline electrolysis cell from Pofile Technology, which is suitable for electrocatalytic reactions under alkaline and liquid flow conditions.
Solid State Oxide (SOFC/SOEC) Electrolysis Water Test Stand: Used for testing solid oxide electrolytes, it can be used for power generation and hydrogen production testing. The SE-12K/60KSOFC/SOEC system testing equipment from Beite Measurement and Control is equipped with fuel gas supply and gas processing analysis solutions.
Anion exchange membrane (AEM) electrolysis water testing bench: mainly used for testing and evaluating the performance of AEM electrolysis water membranes and electrodes, such as the AEM single cell testing device of EVE Hydrogen Energy, which has the characteristics of alkali corrosion resistance and good conductivity.
Classified by testing scale:
Single cell testing bench: used to test the performance of a single electrolytic cell, with a relatively simple structure and low cost, suitable for the performance research of key materials such as electrodes and membranes in the laboratory research and development stage. Kewell's desktop PEM electrolytic cell test bench is suitable for testing single cell hydrogen production systems.
Short stack test bench: It can test short stacks composed of multiple single pools, which can be closer to actual application scenarios and used to evaluate the performance and stability of fuel cells.
Megawatt level test bench: It is a large-scale testing equipment used to test megawatt level electrolytic cell systems, with higher power and gas production capacity, suitable for performance verification and quality inspection before industrial production.
Classified by functional characteristics:
Visual testing platform: such as the PLS-MECF-02 visual dual chamber alkaline electrolysis cell from Pofile Technology, equipped with a visual light window, suitable for photocatalytic water splitting research, allowing for intuitive observation of internal reaction conditions.
Multi functional testing bench: equipped with multiple testing functions, it can perform multiple tests such as polarization curve testing, electrochemical testing, sensitivity testing, durability testing, etc., such as the various testing systems of Beite Measurement and Control.
