Methanol crossover and reaction intermediates are studied in a direct methanol fuel cell (DMFC) by means of 2 D and 13 C MAS NMR spectroscopy. A membrane electrode assembly (MEA) composed of three polymer electrolyte membrane (PEM) layers is used in the DMFC, and the middle PEM film is extracted to perform the NMR measurements (see image).
