项目摘要

Fuel cells have been promoted as a pollution free alternative for energy generation. However, there are several constraints, based around the materials used, which have limited the implementation of this technology. This proposal provides the understanding of the chemical processes occurring in the materials and at the interfaces between the materials which drive the technology and the changes this chemistry causes to the materials. This will enable the design of fuel cell systems and choice of materials to mitigate these changes which reduce performance.The electro-chemical processes which occur in fuel cells (both high and low temperature systems) are not unique to this technology and to demonstrate the efficacy of the study across all temperature ranges (from room temperature to 1200oC) we will also look at the separation of CO2 using dual phase membranes. While still an emerging technology, these membranes encounter similar problems to fuel cells and are extremely exciting as potential short term solutions for existing energy generation systems where CO2 is generated.Several extremely powerful, cutting edge, analytical techniques are available which when applied in real time will allow the observation of the chemistry at atomic level. As a consequence the changes caused by operation of the system can be identified and explained. This project couples the application of existing state-of-the-art techniques with the development of these techniques where necessary to allow researchers to follow the changes as the chemical transformation of fuels into power, or CO2 separation, occur.The potential benefit of this work is that the route to market for all three technologies will be enhanced by a deeper understanding of the chemistry. Hence, the environmental potential of the adoption of these systems will be realised. In addition, the ability to follow processes within working systems will be of great interest to the scientific community working in parallel disciplines such as the design of barriers to prevent corrosion.

燃料电池已被推广为一种无污染的能源生产替代方案。然而，基于所使用的材料，存在一些限制，限制了该技术的实施。该提案提供了对材料中以及驱动技术的材料之间的界面处发生的化学过程以及这种化学对材料造成的变化的理解。这将使燃料电池系统的设计和材料的选择能够减轻这些降低性能的变化。燃料电池（高温和低温系统）中发生的电化学过程并不是该技术所独有的，并且证明了其功效在所有温度范围（从室温到 1200oC）的研究中，我们还将研究使用双相膜分离 CO2。虽然这些膜仍然是一项新兴技术，但它们遇到了与燃料电池类似的问题，并且作为产生二氧化碳的现有能源发电系统的潜在短期解决方案非常令人兴奋。当实时应用时，可以使用几种极其强大的尖端分析技术将允许在原子水平上观察化学反应。因此，可以识别并解释由系统操作引起的变化。该项目将现有最先进技术的应用与必要时这些技术的开发结合起来，以便研究人员能够跟踪燃料化学转化为电力或二氧化碳分离时发生的变化。该项目的潜在好处工作的重点是，通过对化学的更深入了解，将增强所有三种技术的市场途径。因此，采用这些系统的环境潜力将得到实现。此外，在工作系统内跟踪流程的能力将引起从事并行学科（例如防止腐蚀的屏障设计）的科学界的极大兴趣。
