Aim of this work is to present, for the first time, the use of Dynamic Mechanical Analysis as a tool to characterize the thermo-mechanical behavior of green tapes defining the process conditions for the subsequent lamination step. This method was applied on tapes of protonic conductors, key-materials for different applications in the energy sector, from gas separation membranes to solid oxide fuel cells and electrolyzers. The pore former (rice starch) content was found to considerably affect the thermomechanical behavior (elastic and storage moduli, elongation to break, viscosity) of the tape and therefore the lamination process. The temperature required for a proper lamination increases from 50 up to 75 °C passing from the system without rice starch to the one with the highest pore former amount. This work identifies for the first time an optimal lamination viscosity (10¹⁰ Pa s), regardless the tapes formulation, required for a suitable adhesion among the layers.

这项工作的目的是首次展示动态力学分析作为一种工具来表征未加工带的热机械行为，该未加工带定义了后续层压步骤的工艺条件。该方法应用于质子导体的胶带上，质子导体是能源领域不同应用的关键材料，从气体分离膜到固体氧化物燃料电池和电解槽。发现成孔剂（大米淀粉）的含量会显着影响胶带的热机械性能（弹性和储能模量，断裂伸长率，粘度），从而影响层压过程。从没有大米淀粉的体系到具有最高成孔剂含量的体系，进行适当层压所需的温度从50升高到75°C。¹⁰ Pa s），无论胶带的配方如何，各层之间都需要适当的粘合力。
