他是西蒙弗雷泽大学燃料电池科学与技术发展的二级研究员。关于耐用燃料电池的发现研究计划提出了氢燃料电池在零排放重型运输系统（包括卡车、铁路、海洋和航空）中使用的严格耐用性要求的杰出科学前沿。重点是重型卡车和相关的30,000小时的最终使用寿命目标，相当于100万英里，这是轻型汽车的三倍多，对燃料电池和零排放汽车生产商提出了相当大的挑战。主要研究目标是：1)深入了解燃料电池在动态运行条件下从根本原因到失效的关键降解机制；2)开发用于车辆燃料电池寿命预测的建模工具；3)展示运输系统中具有成本效益、可扩展的燃料电池技术的耐用性增强策略。该研究项目的长期愿景是与加拿大不断发展的清洁技术产业合作，开发并商业化市场上最耐用、可靠、可扩展的燃料电池系统。这项研究将利用Kjeang博士开创的一种原始方法，用于燃料电池降解的多尺度、时间分辨x射线可视化。这种方法可以实现小型化燃料电池的非侵入性x射线成像，可以在降解过程中定期应用，从而促进对原生燃料电池环境中的根本原因、降解机制和失效模式进行前所未有的信息丰富的四维评估。由此获得的新的基本认识将随后用于开发新的耐久性增强方法和寿命预测工具。拟议的研究计划旨在响应新发布的加拿大氢战略的行动呼吁，抓住氢的机遇，该战略强调了进一步研发投资的重要性，以“进一步降低成本”和“发现新的突破性技术，使该行业受益”，以保持创新的前沿，并维持加拿大在氢和燃料电池领域的竞争优势。在此背景下，该研究将为耐久性管理创造突破性技术，并降低零排放燃料电池电动汽车的制造和生命周期成本。根据加拿大氢战略，通过与行业的现有合作，成果将有效转化为产品和服务，实现现实世界的利用和相关的经济、社会和环境效益。此外，这项研究将为这个不断发展的行业培养下一代工程师。

Dr. Kjeang is the CRC (Tier 2) in Fuel Cell Science and Technology Development at Simon Fraser University. The proposed discovery research program on Durable Fuel Cells addresses the outstanding scientific frontier on the stringent durability required for hydrogen fuel cell use in zero-emission heavy duty transportation systems, including trucking, rail, marine, and aviation. The emphasis is on heavy duty trucks and the associated ultimate lifetime target of 30,000 hours, equivalent to one million miles, which is more than three times higher than that of light duty vehicles and poses a considerable challenge for fuel cell and zero-emission vehicle producers. The main research objectives are to: 1) Develop in-depth knowledge of the key fuel cell degradation mechanisms from root cause to failure under dynamic operating conditions; 2) Develop modeling tools for fuel cell lifetime predictions in vehicle applications; and 3)Demonstrate strategies for durability enhancement of cost-effective, scalable fuel cell technologies for transportation systems. The long-term vision of this research program is to team up with the growing cleantech industry in Canada to develop and commercialize the most durable, reliable, and scalable fuel cell systems on the market. This research will utilize an original methodology pioneered by Dr. Kjeang for multiscale, time-resolved X-ray visualization of fuel cell degradation. This method enables non-invasive X-ray imaging of a miniaturized fuel cell that can be periodically applied during degradation, thus facilitating an unprecedently informative, four-dimensional assessment of root causes, degradation mechanisms, and failure modes within the native fuel cell environment. The new fundamental understanding thus achieved will subsequently be leveraged to develop novel durability enhancement approaches and lifetime prediction tools. The proposed research program is designed in response to the Call to Action of the newly released Hydrogen Strategy for Canada, Seizing the Opportunities for Hydrogen, which stresses the importance of further R&D investments to "reduce costs further" and "discover new breakthrough technologies to benefit the sector" to stay at the forefront of innovation and sustain Canada's competitive advantages in the hydrogen and fuel cell sector. In this context, the research will create breakthrough technologies for durability management and reduce manufacturing and lifecycle costs of zero-emission fuel cell electric vehicles. Through existing collaborations with industry, the outcomes will be effectively translated into products and services that enable real-world utilization and associated economic, societal, and environmental benefits, in accordance with the Hydrogen Strategy for Canada. Additionally, this research will train the next generation engineers for this growing industry.
