Oxide-based high temperature proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade. This work aims to develop an all ox ....Oxide-based high temperature proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade. This work aims to develop an all oxide-based PEMFC technology using a recently developed sintered and heteropolyacid functionalised mesoporous silica membrane. The utilisation of all-oxide-PEMFCs using non-precious metal catalysts is expected to significantly enhance the power density, reduce costs, and enhance the commercial viability of PEMFC technologies.Read moreRead less

Summary
Carbon-free high temperature vacuum sintering facility. This facility will provide an extremely clean sintering environment for development of advanced materials free from imperfections for applications which range from energy conversion to medical components. It will ensure that Australia is an important international leader in both fundamental research and industrial innovation.
New mesoporous materials for use in high temperature proton exchange fuel cell membranes. A novel high temperature proton exchange membrane based on heteropolyacid (HPA) functionalised mesoporous silica will be developed. This research into the fundamental materials science of novel proton exchange membranes is expected to impact significantly on the advancement and commercialisation of portable fuel cell devices.
Metal-support interactions: single atoms Vs nanoclusters. This project aims to fundamentally understand the catalytic mechanism at an atomic level through metal-metal and metal-metal/support interactions. The optimised configuration of active sites for a specific reaction is consequently identified, providing the design principles of novel catalysts. The precisely control of synthesis for such active sites and assembly of the target active sites into a catalyst will deliver a completely new meth ....Metal-support interactions: single atoms Vs nanoclusters.

The precisely control of synthesis for such active sites and assembly of the target active sites into a catalyst will deliver a completely new methodology for catalyst development. The expected outcomes from this project include new science and knowledge of Chemistry, new design philosophy and strategies for catalysts, and the highly efficient catalysts for electrocatalytic reactions, benefiting Australian renewable energy research and industry.Read moreRead less
