Detecting Cation Contamination in PEM Water Electrolysis

Detecting Cation Contamination in PEM Water Electrolysis: A Nonlinear Frequency Response Approach

SmartProSys researchers from Max Planck Institute for Dynamics of Complex Technical Systems shed new light on this topic.

Metallic ion contamination is a major cause of PEM water electrolyzer failure. Detecting it early, is key to durable green hydrogen production.

In this study, they used the Nonlinear Frequency Response (NFR) method to identify contamination-induced degradation. Even when standard diagnostics showed no change, NFR clearly distinguished healthy from degraded cells, proving its potential as a non-invasive monitoring tool.
