项目摘要

Current polymer electrolyte membrane fuel cells (PEMFC) technology rely heavily on Pt electrocatalysts to drive the anodic and cathodic reactions. Normally, Pt nanoparticles are dispersed onto a high surface carbon support (Pt/C) to maximize the surface area of the catalyst and increased cell performance. While carbon black has been the de facto catalyst support in fuel cell over the last 30 years, it is a liability when it comes to durability since it is prone to corrosion under the highly acidic and oxidative operating conditions of a PEM fuel cell. This is detrimental to the long-term performance of a fuel cell and hinders the longevity of fuel cell devices.****This proposal is focused on the study and enhancement of a new innovative fuel cell support technology, titanium sub-oxides doped with both Mo and Si (TOMS). This new support material has extremely high stability to corrosion and remarkable high electronic conductivity, considerably larger than any other metal oxide-based support developed to date. Because of this, the TOMS support technology is highly attractive for deployment in fuel cell systems for automotive and stationary power applications. It is expected that the results from this project will lead to the development of higher-performing and lower-cost fuel cells, which will enable Canada to meet its clean energy needs.****

目前的聚合物电解质膜燃料电池（PEMFC）技术严重依赖Pt电催化剂来驱动阳极和阴极反应。通常，Pt 纳米颗粒分散在高表面积碳载体 (Pt/C) 上，以最大化催化剂的表面积并提高电池性能。虽然过去 30 年来炭黑一直是燃料电池中事实上的催化剂载体，但它在耐用性方面却是一个缺点，因为它在 PEM 燃料电池的高酸性和氧化操作条件下容易腐蚀。这不利于燃料电池的长期性能，并阻碍燃料电池装置的寿命。****该提案的重点是研究和增强一种新型创新燃料电池支撑技术，即掺杂钛低氧化物钼和硅 (TOMS)。这种新型支撑材料具有极高的耐腐蚀稳定性和显着的高电子电导率，比迄今为止开发的任何其他金属氧化物基支撑材料都要大得多。因此，TOMS 支持技术对于在汽车和固定电源应用的燃料电池系统中部署非常有吸引力。预计该项目的成果将促进性能更高、成本更低的燃料电池的开发，从而使加拿大能够满足其清洁能源需求。****
