Interfacial contact resistance test bench for contact resistance testing
The experimental test bench is capable of carrying ex situ interfacial contact resistance measurement of metallic bipolar plates of electrochemical devices (electrolyzers and fuel cells). Measurements are performed by applying a direct current between two copper plates using a DC power supply, followed by measuring the voltage with a precision multimeter. Evaluation of conductivity of the sample is performed at different compaction pressures (30-1100 Ncm-2).
