 The SPS-ZIF-93 membrane has been developed for use in PEMFC applications. It has demonstrated improved proton conductivity over the SPS membrane, resulting in a 1.9 fold increase in performance. Additionally, it has shown a 79% improvement in maximum power density, reaching 0.52 WCM2 at 0.5 V and 98% relative humidity.
