 Operando Fuel Cell Raman Spectroscopy Cell

The operando Raman spectroscopy cell enables acquisition of Raman spectra of the membrane electrode assembly catalytic layer under normal operating conditions, eliminating interference from supplemental electrolytes. The cell dimensions provide versatility and ease of use in a confocal Raman microscope. The cell assembly includes a 9-pin connector for connection to an EZstat-Pro potentiostat/galvanostat and temperature controllers. The EZstat-Pro controls the cell potential or current, and the temperature of the cell, reactant transfer lines and humidifiers. The cell features a pin-style upper flow field to optimize flow distribution around the quartz window.
