Categorization of sulfonated ionomer vibrational modes by exchange site symmetry Open
The application of polymer electrolytes to devices such as batteries and fuel cells requires a detailed understanding of how the exchange site varies under different conditions. The categorization of sulfonated ionomer side-chain IR group …
Operando Raman Micro-Spectroscopy of Polymer Electrolyte Fuel Cells Open
Operando Raman micro-spectroscopy of the membrane electrode assembly (MEA) of a fully operating hydrogen/oxygen Nafion electrolyte fuel cell is described. Coarse depth profiling of the fuel cell system enabled appropriate positioning of th…
