In-situ X-ray spectromicroscopy study of bipolar plate material stability for nano-fuel-cells with ionic-liquid electrolyte

Abstract

This paper reports a pioneering application of soft X-ray imaging and spectromicroscopy to a hot material stability issue in fuel-cell (FC) technology: the corrosion of metallic bipolar plates in ionic-liquid-based nano polymer electrolyte membrane (PEM) FCs. Using the potential of the X-ray scanning microscopy for in situ characterisation of complex multi-material systems in electrochemical environments with sub-micrometer lateral resolution, we study the electrochemical behaviour of Fe electrodes in contact with the room-temperature ionic liquid (RTIL)1-butyl-1-methyl-pyrrolidinium bis (trifluoromethylsulfonyl) amide ([BMP][TFSA]) in a nano fuel-cell fabricated by lithography. Thanks to the properties of this RTIL, an open electrochemical cell could be used in vacuum (10-6 mbar). The possibility of imaging electrochemically induced morphological features in conjunction with local spectroscopic analysis, yields details of the space distribution and chemical correlations of the corrosion products.
