Specific electrical contact resistance (mOhm.cm 2 ).
W: Width of GDLs (mm).L: Width of metallic indenters (mm).
d: Distance between metallic indenters (mm).Rt: Total electrical resistance of the two metallic contacts and the GDL (Ohm).Rs: Sheet resistance (Ohm / or Ohms per square).Aeff: Specific contact area (mm²).Cρc: Contact resistance absolute difference between cycles (mOhm.cm 2 ).RCρc: Contact resistance relative difference between cycles (%).
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.
