Product Brief The N600C Carbon Paper Air Permeability Rate Tester is designed and developed in accordance with GB/T 20042.7-2014. Adopting the differential pressure method as its testing principle, it is professionally used for measuring the air permeability rate of various types of carbon paper for proton exchange membrane fuel cells (PEMFC). Testing Principle Based on the differential pressure method, the sample is placed between two fixtures, forming a constant differential pressure on both sides of the sample. Driven by the differential pressure, gas flows from the high-pressure side through the sample to the low-pressure side. The air permeability rate of the carbon paper is calculated based on the transmission flow rate, sample thickness, test area, and test differential pressure.
