Degradation Influence of Single Solvents on the Structural Integrity of Ionomer Membranes: Morphological, Structural and Electrochemical Properties.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Sustainable energy technologies like the fuel cell have been explored as potential substitute energy sources to lessen pollution and reliance on fossil fuels. At the very core of fuel cells are ionomer membranes, particularly used in proton exchange membrane fuel cells (PEMFCs) and other electrochemical devices such as electrolyzers. This research aimed to study the morphological and structural changes of ionomer membranes in the presence of single solvents. The ionomer membranes were partially dissolved in water (polar protic solvent) and dimethyl sulfoxide (polar aprotic solvent) and analyzed using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and electrochemical impedance spectroscopy (EIS). The results showed that water, being a polar protic solvent, interacted not only with the hydrophilic sulfonic acid regions of the membranes but also with the hydrophobic fluorocarbon backbone as seen in the EDX results. On the other hand, DMSO, which is a polar aprotic solvent, caused more visible changes in both structure and surface appearance. By examining these relationships more closely, this research deepened our understanding of how single solvents affect ionomer membranes to improve ionomer membrane fabrication methods.
