The invention discloses a fuel
cell bipolar plate and
carbon paper interface
contact resistance nondestructive measurement device which comprises a base, a micro resistance meter and a controller, the micro resistance meter and the controller are fixed on the base, and a left clamping device and a right clamping device are respectively arranged above the base. The left clamping device and the right clamping device are both provided with auxiliary fixing mechanisms used for sucking and bulldozing
carbon paper, and the left clamping device and the right clamping device clamp the
carbon paper, the bipolar plate and the carbon paper and then are connected with the micro-resistance meter in series for
contact resistance testing. A surface changing mechanism capable of fixing the bipolar plate and driving the bipolar plate to turn over and change the surface is also arranged between the left clamping device and the right clamping device, the bipolar plate is driven to rotate by 180 degrees through the surface changing mechanism after the first
contact resistance test is finished, the contact
resistance test is performed again, and the average value of the two test results is taken as the final test result. According to the invention, the test carbon paper can be better protected, and meanwhile, the measurement accuracy can be improved.
