Project summary description:
This project aims to address a longstanding challenge in the development of direct ammonia fuel cells for the utilisation of ammonia as a green energy carrier. It proposes to develop advanced hydroxide ion conductive membranes based on novel porous framework materials to achieve high hydroxide ion conductivity and lower ammonia crossover simultaneously, thereby substantially enhancing the energy efficiency of direct ammonia fuel cells.

The proposed research expects to create new knowledge in the fields of membrane science and energy. The successful development of advanced membranes will improve the efficiency of storage of intermittent and fluctuating renewable resources.

Building upon our fundamental understanding of ultrafast selective ion transport in porous framework materials-based nanochannel membranes, this project aims to develop the novel covalent organic frameworks (COFs)-based membrane as the hydroxide exchange membrane (HEM) for ammonia fuel cell technology to address the unresolved challenges including the low hydroxide ion conductivity, cross-over of ammonia gas molecules, and low durability of conventional polymer membranes.
