상세 정보

This product is a Gore 788.12 proton exchange membrane, engineered for use in energy-related research and fuel cell applications. With a nominal thickness of 12 µm, it offers low proton resistance values—under 120 mohm·cm² at 80°C and 30% relative humidity, and a conductivity of 30 mA/cm²/MPa under 50% RH conditions. The membrane exhibits balanced mechanical properties, with longitudinal tensile strength of 71 MPa and transversal strength of 76 MPa, along with less than 5% area expansion upon hydration. Its high mechanical durability and low gas permeability make it particularly suitable for environments requiring robust physical integrity, such as backup power systems, forklifts, range extenders, portable devices, and automotive applications. This combination of strength and gas barrier performance helps reduce overall system costs while maintaining reliable operation across diverse conditions.

Differences
1. Thickness	8um	12um
2. Performance Focus	Focuses on providing high power density under dry conditions, suitable for passenger vehicle applications that require higher fuel cell power output and may face relatively dry environments.	Emphasizes high mechanical durability and low gas permeability, excelling in applications where high membrane mechanical strength and strict gas permeability control are required, such as backup power sources, forklifts, etc., which may experience more physical vibrations and varying gas environments.
3. Application Focus	Mainly for the passenger car market, meeting the specific fuel cell performance needs of passenger cars during driving, such as quick acceleration and long range.	Has a broader application scope, covering not only the automotive field but also backup power sources, range extenders, forklifts, and portable devices, with a focus on stability, durability, and versatility.
