Title: High Temperature Membrane with Humidification-Independent Cluster Structure

The objective of this project was to develop high temperature membranes to facilitate the wide-spread deployment of hydrogen fuel cells. High temperature membranes offer significant advantages in PEM system operation, overall capital and operating costs. State-of-the-art Nafion-based membranes are inadequate for the high temperature operation. These conventional membranes become unstable at higher temperatures (90-120°C) and lose their conductivity, particularly at low relative humidity. In this program, alternate materials were developed to enable fabrication of novel high performance composite membranes. FCE’s concept for the multi-component composite membrane, named mC2, has been used in the design of more conductive membranes.
