Mega EIS
Code: 120Product detailed description
For fuel-cell stacks, power stage is built from EIS load modules. Your stack can have up to 1 000 cells and provide current up to 2 kA. System is designed for cooperation with external DC load which may handle most of the stack power (up to 300 kW). Maximum internal power dissipation of MegaEIS power stage can be up to 20 kW. System is water-cooled.
For electrolyzers, power stage is extended by internal or external power supply, so the system works as regulated power source, capable of EIS measurement.
EIS acquisition runs simultaneously on all channels, so the system is suitable for rapid and precise analysis in R&D, for QA in manufacturing, or in service diagnostics. MegaEIS also provides DC cell voltage monitoring and enables characterization using important electrochemical methods – Polarization Curves, Chronopotentiometry and Chronoamperometry, Load Cycling, Current Interrupt Technique, etc.
