Product BriefThe N600C Carbon Paper Air Permeability Rate Tester is designed according to GB/T 20042.7-2014. Using the differential pressure method, it is intended for quantitative measurement of air permeability of carbon paper used in proton exchange membrane fuel cells (PEMFC).
Testing PrincipleUsing a controlled differential pressure across the sample, gas flows from the high-pressure side through the specimen to the low-pressure side. Permeability is calculated from transmitted flow rate, sample thickness, test area and applied differential pressure.
