Practical Hydrogen Storage for Fuel Cells Electrical Vehicles by Confined Ammonia Borane System. Practical hydrogen storage is critical to make the hydrogen economy a reality, in particular for fuel cells electrical vehicles (FCVE).

Practical hydrogen storage is critical to make the hydrogen economy a reality, in particular for fuel cells electrical vehicles (FCVE). However, currently there is no approach to satisfy the requirements of hydrogen storage for FCVE, e.g. fulfill the US Department of Energy target for practical hydrogen storage. This project is proposed to develop a new strategy to achieve the goal of practical hydrogen storage which, if successful, will make FCVE possible in Australia in the near future. It will also be beneficial for reducing the dependence on exported oil and possibly solving critical environmental issues, and thus benefits the Australian economy.Read moreRead less
Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U ....Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U.S.A. An understanding of the factors that maximise the containment of cracks is essential to the design and development of the next generation of advanced layer composites for many biomechanical and other engineering applications.Read moreRead less
