High-Temp Proton Membrane for Hydrogen Purity, Efficiency
High-Temperature Proton-Conducting Membranes
Tags: Monash University, Australia, Energy & Environment
Researchers at Monash University have developed a high-temperature proton-conducting membrane with excellent thermal stability and mechanical strength, capable of operating up to 250°C without degradation. This membrane, made from monolayer nanosheets, exhibits nearly 100% selectivity in separating hydrogen from H₂/CO₂ mixtures and offers a hydrogen permeance of 61 GPU. It also maintains a current density three times higher than commercial alternatives in fuel cell applications. The technology has significant applications in fuel cells, hydrogen purification, and water electrolysis, supporting the shift toward net-zero emissions. This membrane technology offers a safer, efficient alternative to existing options, as it can operate at intermediate temperatures without the need for noble metal catalysts.
