New harmonized test protocol for accelerated stress tests of the JRC for water electrolysers (AWE, PEMWE, AEMWE)

The Joint Research Centre (JRC) of the European Union has published a harmonized test protocol for water electrolyzers in 2024. These accelerated stress tests (AST) enable a reliable assessment of electrolyzer stack performance degradation under real operating conditions.

A major advantage of this standardization is that measurement data from different electrolyzers can now be compared. Research institutions and companies can conduct precise analyses and systematically improve their systems. This new testing framework also provides a uniform evaluation basis, especially for integrating renewable energy into electrolysis processes.

A key element of the tests is electrochemical impedance spectroscopy (EIS). It allows for a precise analysis of the electrochemical properties of electrolyzer cells, detects performance losses at an early stage, and helps optimize operating parameters.

The SIVONIC EIS meter is specifically optimized for these measurements. It delivers high-precision data, even at high currents and demanding operating conditions, supporting researchers and engineers in making electrolyzers more efficient and durable.

With EU standardization and advanced measurement technology like the SIVONIC EIS meter, an efficient and sustainable hydrogen production is now within reach.
