“…4.25 325 [25] 120 [26] 0.649 [27] Toray carbon papers have the highest through-plane thermal conductivity among different available carbon papers with similar porosity due to the contribution of the binder to heat transfer in the carbon paper GDL [16]. The binder fills the gaps between fibers and provides a better contact.…”

“…They reported that through-plane resistance directly influences the resistance overvoltage of a fuel cell and that in-plane resistance influences not only the overvoltage but also the in-plane distribution of the local current density in a cell [10]. Parikh et al used an in situ 4-probe method inside a SEM to measure the electrical resistance of carbon fibers [11]. They reported a measured value of around 60 U and that the Kelvin resistance was reduced to approximately one-half through bending deformation process.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
