Ultra-efficient CO2 Electrolyser with Microchanneled Bipolar Membrane (2026-2029)
Abstract
This DECRA project aims to develop innovative bipolar membrane (BPM)-based CO2 electrolyser that maximize their potential for energy and carbon efficiency. The key strategy is to design and integrate advanced three-dimensional microchannels within BPMs. This integration is expected to precisely control BPM interfacial mass transport and electric field. Expected outcomes include new microchaneled BPM interface model, new high-performance microchanneled BPM, and new BPM-based CO2 electrolyser with practically viable energy and carbon efficiency. This is expected to provide significant benefits such as advancing Australia's CO2 capture and utilization and accelerating the transformation of its energy industry to achieve net zero emission.
