H 2 and carrier gas at 1atm accounting for the saturation pressure of water at the operating temperature (50–80°C). 5. The exhaust of the anode should be connected to a gas –water separator . Gas permeability in coal characterizes the migration capacity of gas in coal, and it is an important parameter influencing the gas flow in a coal seam. Energy dissipation and energy release are important causes of rock mass failure. By utilizing a THM-2-type thermo-fluid–solid coupling test system for gas-bearing coal developed at Chongqing University, . Gas Permeability Test Protocol for Ion-Exchange Membranes. . water is a growing topic of interest due to the advantages of employing membranes in hydrogen production efficiency and system safety over the traditional alkaline water electrolysis. Ion-exchange membranes with low gas permeability are highly desirable for stable and safe operation .

This test method provides for the determination of (1) gas transmission rate (GTR), (2) permeance, and, in the case of homogeneous materials, (3) permeability.
Permeability Gas Testing. Pure gas permeability results were obtained using the pressure-rise time-lag method [17–20]. Membranes were exposed to individual gases, like H 2, CH 4, and CO 2. In a typical experiment, both sides of the membrane are evacuated to an equal vacuum. . The pure gas system can reach about 70 °C, whereas mixed gas .
Labthink C130H Gas Permeability Tester is based on manometric method and conforms to ASTM D1434, while C206H Oxygen Transmission Rate Test System is based on the coulometric sensor method and conforms to ASTM D3985 Two primary methods are employed for gas permeability measurement: the manometric method and the equal pressure method.
The system can measure permeabilities varying from 10-4 cm/sec to 10-9 cm/sec. With the appropriate test cells, this one system can determine the permeability of silts and clays within minutes. Triaxial and stress path testing can easily be performed with added software because the hardware and accessory configuration is ready. This study discusses 1) technical challenges in conducting the gas-liquid relative permeability test on HBS, 2) experimental methodology and setup to overcome the technical challenges, 3) preparation of a sandy HBS specimen with a natural-like pore habit and execution of single-phase (brine) permeability and gas-liquid (methane-brine) relative .
