FSC is using a Mark-10 motorized test stand, digital force and torque gages and torque test stand for contact resistance measurement and torsion measurement in its labs.
According to Jeff Hung, adjunct professor and technical specialist at FSC, these instruments are used for both funded research and student experiments to test the properties of different materials, specifically compression and torsion.
For its fuel cell experiments, FSC measured the interfacial contact resistance (ICR) between the gas diffusion layer (GDL) and various bipolar plate materials. “Mark-10’s equipment enabled us to very precisely test and easily measure the contact resistance between the plates as we applied a certain pressure,” says Hung. “The results were very accurate, and we were able to get consistently repeatable readings.”
