Carbon Paper Gas Permeability Tester N600C Introduction The carbon paper gas permeability tester N600C is designed and developed according to GB/T20042.7-2014. It adopts the test principle of pressure difference method and is professionally used for the air permeability test of various types of carbon paper used in proton exchange membrane fuel cells. Test principle Based on the differential pressure method, the sample is placed between two fixtures, creating a constant pressure differential across the sample. This pressure differential causes gas to flow through the sample from the high-pressure side to the low-pressure side. The carbon paper's transmittance is calculated based on the flow rate, sample thickness, test area, and test pressure differential.
