  "abstract": "Hot-pressing is a critical yet insufficiently understood step in the fabrication of membrane electrode assemblies (MEAs) for proton exchange membrane fuel cells (PEMFCs). Here, a design-of-experiments approach based on a Central Composite Rotatable Design (CCRD) is employed to decouple the effects of temperature, pressure, and compression time in catalyst-coated substrate MEAs. Strong non-linear interactions between processing parameters are identified, highlighting the limitations of conventional optimization strategies. Optimal conditions (144°C, 5.0 MPa, 2.1 min) yield a peak power density of 1055 mW cm −2 under H 2 /O 2 at 95% relative humidity, with excellent agreement between predicted and experimental values (∼1% error). Morphological analysis using SEM reveals qualitative differences in interfacial morphology between higher- and lower-performing MEAs, consistent with a possible contribution of interfacial quality to performance. The response-surface framework proved applicable under reduced humidity and air operation, with distinct optimal hot-pressing parameters identified for each condition, confirming that MEA fabrication must be specifically optimized for the targeted operating environment. Optimal hot-pressing parameters were found to be system-dependent. This work establishes a predictive framework for scalable and reproducible fabrication of high-performance PEMFC MEAs.",
