Implication

Comprehensive review identifies manufacturing variability sources in proton exchange membrane fuel cells, highlighting quality control pathways for reproducible scale-up.

Key Points

To establish workflow-centric links between manufacturing steps, defect formation, and performance variability in proton exchange membrane fuel cells to guide reliable scale-up.
Reviewed fabrication processes across gas diffusion layers, catalyst layers, catalyst-coated membranes, and bipolar plates to identify defect propagation pathways.
Synthesized quality-control diagnostics, compression and wettability characterization, assembly practices, and standardized break-in and validation testing protocols.
Accumulation of minor variations in coating uniformity, porous structure, interfacial contact, compression, hydration history, and conditioning drives major product-level performance scatter.
Integrating rigorous screening of compression-dependent properties and wettability with harmonized activation protocols provides a practical pathway to achieve reproducible durability.
