Graphene oxide Subject

CB, and in particular Vulcan XC-72, is the standard support material in fuel cell research. Therefore, it is hardly surprising that most recent publications do no longer focus on ways to describe, analyze, and optimize the support, but rather report on strategies to, for example, increase the dispersion of the catalytically active metal nanoparticles on the carbon surface by various treatments [43-47]. Apart from that, also the investigation of CB composites, such as CB blended with CNT [48] and CB/reduced graphene oxide [49], came into the focus of recent fuel cell research, as well as its application in the microporous layer (MPL) of the GDLs, which are not subject of this chapter [50, 51]. In addition, the comparison of low-surface-area Vulcan XC-72 with high-surface-area black pearls or Ketjen-black with respect to their electrochemical properties, capacitive behavior [52], and durability [53] has been a frequent subject of recent publications.
