Abstract
The applied preparation procedure of membrane submersion in an aqueous salt solution for 24 h is a widespread method for ion exchange in polymer membranes.[3-5] The present TGA-GC/MS analysis shows that in some cases this method has to be regarded with caution as the ion exchange might not be complete. To obtain reliable electrochemical data (e.g. conductivity) of PBI-CO32- in further studies, modification of the ion exchange procedure is recommended. The hyphenation of TGA and GC/MS is an adjuvant tool for the investigation of materials like polymer membranes for fuel cell use as the degradation products of each decomposition step can be analyzed separately to get useful information for further improvement of the material stability. Furthermore the progress of preparation processes can be monitored, as it was exemplified in this work by the ion exchange in a polybenzimidazolium membrane.
