Hephas Energy HS-Series Equipped with MegaEIS for PEMFC Stack Performance Diagnosis
As the demand for high-performance and high-power fuel cell stacks for heavy-duty vehicles continues to grow, precise analysis and optimization have become essential. Hephas has integrated Kolibrik's multi-channel EIS (Electrochemical Impedance Spectroscopy) technology into the HS-series fuel cell stack testing system.
With advanced impedance analysis capabilities, the EIS function enables researchers and engineers to gain deeper insights into stack performance, degradation mechanisms, and efficiency improvements, making it an indispensable tool for fuel cell development and validation.
Hephas has introduced the HephaStaion stack testing bench, a popular standard in fuel cell stack testing systems.
“We are committed to delivering the best solutions on the market, so we have carefully evaluated various options before selecting Kolibrik's multi-channel EIS technology. The Kolibrik MegaEIS System meets all demanding requirements for accuracy, high currents, and high power in fuel cell stack analysis,” says the CEO of Hephas Energy, Jerry Chen.
“We really appreciate Kolibrik’s R&D and support team as they provide very quick support and allow smooth implementation when it is needed. They are always willing to help satisfy our customer's specific needs,“ adds Senior SW Manager, Adam Lo.
The HephasStation is suitable for following applications:
- PEMFC/PEMEC short stack or long stack research
- Stack design validation and performance measurement
- Operation parameter sensitivity testing and accelerated stress testing
- Stack long term durability testing
Hephas Energy also designs and manufactures test stations for single-cell testing. For these, Kolibrik high-current potentiostats with EIS are a perfect match and allow analysis of the single cells within fuel cells and electrolyzers, further assisting end customers in optimizing and improving the efficiency.
MegaEIS is a Multi-Channel EIS Analyzer for Hydrogen Fuel Cell, Electrolyzer and Battery Stacks. The latest versions of MegaEIS can handle voltage up to 1000 V and currents up to 2000 A and measure 1024 channels simultaneously up to 100 kHz.
Hephas Energy is one the leading hydrogen and fuel cell test equipment supplier of test stations for PEMFC/SOFC fuel cells and electrolyzers. The product portfolio including from MEA, short stack and large stack up to 300kW.
