SBIR Phase II: Carbon Monoxide-Tolerant Anode Catalysts for Proton Exchange Membrane Fuel Cells via Combustion Chemical Vapor Deposition

这个小型企业创新研究（SBIR）二期项目旨在实施燃烧化学气相沉积（CCVD）工艺，为质子交换膜燃料电池（PEMFC）生产需要重整燃料原料气的阳极电催化剂层。在第一阶段，证明了使用CCVD制备Pt:Ru电催化剂作为无负载的金属纳米颗粒是可能的。这些电催化剂层的电化学行为与使用湿化学方法在碳载体上制备的市售Pt:Ru电催化剂类似，但可以直接沉积在气体扩散介质和质子交换膜上。二期项目将涉及催化剂组成的优化，继续开发用于大规模生产膜电极组件（MEAs）的卷筒膜涂层技术，并通过生产设备的建设和许可将该技术商业化。市场对燃料电池有着巨大的兴趣，燃料电池公司在技术和市场资本化方面的大量投资说明了这一点。例如，戴姆勒-克莱斯勒计划在2004年生产燃料电池汽车，并计划投资超过14亿美元来实现这一目标。然而，为了商业可行性，电催化剂层的性能和成本必须得到改善。MCT如果成功，可以在这两个领域做出贡献。

This Small Business Innovation Research (SBIR) Phase II project seeks to implement a Combustion Chemical Vapor Deposition (CCVD) process for the production of anode electrocatalyst layers for Proton Exchange Membrane Fuel Cell (PEMFC) applications requiring reformate fuel feed gas. In Phase I it was demonstrated that fabrication of Pt:Ru electrocatalysts as unsupported, metallic nanoparticles is possible using CCVD. These electrocatalyst layers behave electrochemically in a similar manner to commercially available Pt:Ru electrocatalysts prepared on carbon supports using wet chemical methods, but can be deposited directly onto both gas diffusion media and proton exchange membranes. The Phase II project would involve optimization of catalyst composition, continued development of web coating technology for mass production of membrane electrode assemblies (MEAs) and commercialization of the technology through construction of production equipment and licensing.Fuel cells are of huge interest to the marketplace, as illustrated by sizable investments in the technology and market capitalization of fuel cell companies. For example, Daimler Chrysler has targeted the year 2004 for planned production of fuel cell vehicles, and has slated more than $1.4 billion in investments to reach that goal. However, for commercial viability, performance and cost of the electrocatalyst layers must be improved. MCT, if successful, could contribute in both arenas.
