To provide insights for the development of more robust and long-lasting PEMFC materials.

Main Methods:

A novel magnetic array with 16 sensors was designed and integrated within a 25 cm² area.
The sensor array was used for direct scanning and imaging of PEMFC performance during degradation.
Results were validated using established degradation mechanism analysis and material characterization techniques.

Main Results:

The magnetic sensor array successfully imaged the heterogeneity of PEMFC performance during degradation.
The imaging technique provided practical, real-time data on fuel cell degradation.
Validation confirmed the accuracy and potential of the developed method.

Conclusions:

The designed magnetic sensor array offers a practical and effective solution for analyzing PEMFC degradation heterogeneity.
This non-destructive imaging approach can guide the development of more durable fuel cell components.
The technology holds significant potential for advancing fuel cell research and commercialization.
