Abstract Proton exchange membrane fuel cells (PEMFCs) demonstrate exceptional efficiency in converting hydrogen into electricity and hold great promise for mitigating carbon emissions. However, the high loading of platinum (Pt) (0.2–0.35 mg Pt cm −2 ) cathode catalytic layer (CL) poses a significant obstacle to commercialization PEMFCs. Although current research has succeeded reducing usage CL, corrosion remains major issue that leads decreased output power density shortened service life. The enhancement support stability greater challenge compared improvement intrinsic Pt‐based alloys, primarily due thermodynamic instability during practical operating conditions. Recently, extensive efforts are dedicated exploiting advanced supports through utilization innovative nanostructure design synthesis techniques, as well profound mechanistic insights. This review highlights intriguing advancements modification materials, while also summarizing underlying mechanisms potential factors impact reaction carbon. general ideas strategies development materials with desirable nanostructures physicochemical properties outlined detail low‐Pt CL highly efficient mass transfer superior stability.

Abstract 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 existing techniques relying on material characterization. In this work, a designed magnetic array integrating 16 sensors within 25 cm 2 space used for direct scanning imaging PEMFC performance during its degradation. Results are validated through mechanism analysis characterization, confirming potential in guiding development durable materials.
