Prof. Zhang Xiao Secures Highly Competitive Innovation and Technology Fund for Fuel Cell Technology

Prof. ZHANG Xiao, Assistant Professor and Presidential Young Scholar of the Department of Mechanical Engineering, has been awarded the Innovation and Technology Fund - Innovation and Technology Support Programme (ITF-ITSP) research grant of around 1.4 million Hong Kong dollars for a Nanotechnology and Materials Science project. The project is titled "Mass Production of Low-cost High-efficiency Catalysts for Anion Exchange Membrane Fuel Cells (AEMFCs)". As the project investigator, Prof. ZHANG will lead a 1.5-year project, in collaboration with Siphone Science and Technology Limited. Anion exchange membrane fuel cells (AEMFCs) offer a promising alternative to proton exchange membrane fuel cells (PEMFCs) due to their ability to use non-precious metal catalysts with reduced costs. However, the sluggish anodic reaction of AEMFCs, i.e., hydrogen oxidation reaction (HOR), requires a higher amount of platinum (Pt) catalysts, resulting in higher costs and posing a significant economic challenge for the development of high-performance AEMFCs.  This project aims to address this challenge by mass production of low-cost, but efficient HOR catalyst. Isolated Pt on metallic substrates using a hydrothermal and dipping strategy developed by the project group will be created, which can produce 3000-mg-catalysts/time/batch, with the HOR activity nearly ten times higher than that of commercial catalysts. The technology developed in this project has a high potential for commercialization as it can be easily applied to existing catalyst development and fuel cell production lines. Launched in November 1999, the Innovation and Technology Support Programme (ITSP) (Platform & Seed) aims to support applied research and development (R&D) projects undertaken by R&D Centres or designated local public research institutes, aiming to transfer the R&D results to local industries, with strong commercialisation potential or exploratory and forward-looking in nature.

ME PhD Graduate achieves the PolyU PhD Thesis Award for Merit

We are delighted that Dr FAN Haiyan, a PhD graduate from the Department of Mechanical Engineering, has received the competitive PolyU PhD Thesis Award for Merit. The PolyU Graduate School establishes the PhD Thesis Award to recognize, reward and promote the distinguished research achievements by graduating PhD students. There are two award classes, namely Outstanding and Merit, recognizing students’ performance of different levels. In 2024, there were only two awardees across the entire university. Dr Fan completed her PhD under the supervision of Prof. SU Zhongqing and has demonstrated exceptional research achievements through her graduating thesis.   Thesis Title: Non-Hermitian Topological Phases in Elastic and Acoustic Lattices - For contribution to precise sound control and defend against intrusion by small underwater targets Chief Supervisor: Prof. SU Zhongqing Natural materials usually have inherent acoustic characteristics that are difficult to meet the special needs in precise sound control. In this thesis, the proposed metamaterials show unprecedented abilities to engineer the characteristics of sound including but not limited to amplitude, phase, frequency and mode shape, thereby improving sound detection resolution and enhancing the signal-to-noise ratio. This thesis starts with one-dimensional (1D) metamaterials with additional loss treatments to produce a gathering effect of the weak acoustic signals, which amplifies the signals by 9 times. Then, we extend to a two-dimensional (2D) space, achieving high directivity anti-interference sound wave beam based on the valley Hall effect, solving the problem that target acoustic signal propagation is susceptible to interference. Last but not least, a three-dimensional (3D) metamaterial with fluid-solid interaction coming into play which improves the identification ability of underwater small target acoustic signals. These works offer potential applications in acoustic detection and identification of underwater small targets.
