摘要
En 中文
Analyzing degradation heterogeneity of proton exchange membrane fuel cell (PEMFC) while maintaining high practicality is consistently challenging, primarily due to the destructive and costly nature of existing techniques relying on material characterization. In this work, a designed magnetic array integrating 16 sensors within 25 cm2 space is used for direct scanning and imaging of PEMFC performance heterogeneity during its degradation. Results are validated through degradation mechanism analysis and material characterization, confirming its potential in guiding the development of durable materials. Sensing PEMFC degradation heterogeneity with high practicality is consistently challenging. A designed magnetic array integrating 16 sensors within 25 cm2 space is easily-implemented and non-destructive for direct imaging of performance heterogeneity during PEMFC degradation, providing insights into structure disintegration and material fracture. The magnetic array is equally effective for other types of batteries such as lithium-ion batteries, etc. image
