Description
Overview
GORE-SELECT® M765.08 is an ultra-thin, ePTFE-reinforced proton exchange membrane developed for high-performance PEM fuel cells. With a nominal thickness of 8.5 μm and low proton resistance under low-humidity operating conditions, it is designed to support high power density while maintaining dimensional stability and mechanical strength. M765.08 is particularly suited to passenger-vehicle fuel cell systems and other applications requiring compact, high-output stack designs.
