Low-Temperature Fuel Cell Workshop

摘要提案题目：低温燃料电池研讨会提案编号：cts -0522449首席研究员：Thomas fuller机构：佐治亚理工学院将于6月组织为期两天的研讨会，以确定应对低温燃料电池挑战的科学和工程需求。能量的储存和转换对社会至关重要，燃料电池是一种将化学能转换为电能的有效手段，几乎没有排放。特别是，低温（低于200℃）燃料电池非常适合使用氢燃料。最近的报告已经确定，开发具有成本效益、耐用性和安全性的燃料电池系统是21世纪的关键研究挑战。研讨会的目的是将具有低温燃料电池专业知识的跨学科科学家和工程师聚集在一起。具体目标是1)确定低温燃料电池技术的差距，2)描述满足这些关键研究需求的技术方法，以及3)为低温燃料电池的基础研究制定议程，以推进多个学科的知识。低温燃料电池的发展取得了重大进展。尽管如此，很明显，目前的技术还远远达不到最终的要求，需要在基本的理解方面作出重大努力。讨论的起点将是评估低温燃料电池的现状、最终用途要求、现有能量转换系统的能力和局限性。这些信息将通过汽车和能源公司的科学家、工程师和专家之间的交流获得。这些挑战被分解为以下子主题：1)质子导体，2)电催化，3)传输，特别是在低于水冰点的温度下，4)建模和仿真，5)系统集成。就更广泛的影响而言，本次研讨会的发现将发表在《电化学学会杂志》上。因此，这些发现将被广泛传播，并对氢经济的发展、满足未来能源需求的技术以及促进跨学科研究所需的教育举措产生广泛影响。

AbstractProposal Title: Low-temperatue Fuel-cell WorkshopProposal Number: CTS-0522449Principal Investigator: Thomas FullerInstitution: Georgia Institute of TechnologyA two-day workshop in June will be organized to define science and engineering needs addressing challenges for low-temperature fuel cells. Storage and conversion of energy is critical for society, and fuel cells are an efficient means to convert chemical energy into electrical energy with little or no emissions. In particular, low-temperature (less than 200 C) fuel cells are well suited for operation with hydrogen fuel. Recent reports have identified the development of cost-effective, durable, and safe fuel-cell systems as a key research challenges in the 21st Century. The purpose of the workshop is to bring together an interdisciplinary group of scientists and engineers with expertise in low-temperature fuel cells. The specific objectives are to 1) identify gaps in low-temperature fuel-celltechnologies, 2) describe technical approaches to meet these critical research needs, and3) establish an agenda for basic research in low-temperature fuel cells necessary toadvance knowledge across several disciplines. Significant progress has been made in the development of low-temperature fuel cells. Nonetheless, it is clear that present technology falls far short of the ultimate requirements, and significant effort in fundamental understanding is warranted. The starting point for the discussion will be the assessment of the status of low temperature fuel cells, the end-use requirements, capabilities and limitations of existing systems for energy conversion. This information will be obtained through an exchange between scientists and engineers and experts in the automotive and energy companies. The challenges are broken down into the following subtopics: 1) proton conductors, 2) electrocatalysis, 3) transport, particularly at temperatures below the freezing point of water, 4) modeling and simulation, and 5) systems integration. In terms of the broader impacts, the findings of this workshop willbe published in the Journal of the Electrochemical Society. Thus, these findings will bewidely disseminated and have broad impact on the development of a hydrogen economy,technologies to meet future energy needs, and educational initiatives needed to fosterinterdisciplinary research.
