N600C Carbon Paper Permeability Tester
Product Introduction
N600C Carbon Paper Permeability Tester is designed and developed in accordance with GB/T20042.7-2014. Adopting the differential pressure test principle, it is professionally used for testing the permeability of various types of carbon paper for proton exchange membrane fuel cells.
Test Principle
Based on the differential pressure test principle, the sample is placed between two fixtures, forming a constant pressure difference on both sides of the sample. Under the action of pressure difference, gas flows from the high-pressure side through the sample to the low-pressure side. The permeability of carbon paper is calculated according to the permeation flow rate, sample thickness, test area and test pressure difference.
