This presentation will highlight how a conventional high temperature press process, e.g., calender rolls, straighten or flatten the material, consequently reducing porosity drastically. Alternatively, this work shows the benefit of pressing the material at a constant pressure, by means of an isobaric double belt press. Isobaric double belt presses prevent flattening of the surface structure, thermally treating the MEA with high precision, and increasing the manufacture scalability compared to a conventional calender process. Moreover, it offers an opportunity to produce an entire cell stack, roll-to-roll, or roll-to-plate process.
