Abstract : Front Cover: The cover illustrates proton (H)‐ and sodium (Na)‐ form of sulfonated poly(ether ether ketone) membrane films. In the image, the film H‐membrane undergoes degradation and cross‐linking upon heating to 190 °C, resulting in a red color of the material, while the Namembrane remains unchanged. The significantly enhanced thermal stability of Na‐membranes allows for processing at elevated temperatures without adverse effects. Further details can be found in the article by B. T. Koziara, E.
