提案编号：CTS-0226095主要研究者： 斯特凡·T Thynell附属机构： Pennsylvania State UniversityProposal Title：Anisotropic Thermal Transport in Fuel CellsAbstract该提案涉及PEM燃料电池膜系统中各向异性热传输和水管理之间的耦合。 水管理对于燃料电池的有效运行至关重要。 拟议的研究将包括气体扩散层和电解质的各向异性热导率的测量，以及一个5平方厘米的操作燃料电池的气体和表面温度。 一个分析模型将考虑正交各向异性导热系数，以及流体力学，物种运输，平流和电化学。 结果将对各向异性热传输的基本理解产生影响，将解决PEM燃料电池的关键水管理问题，并将使机械工程专业的学生接触到通常被认为是学科之外的技术领域。

Proposal Number: CTS-0226095Principal Investigator: Stefan T. ThynellAffiliation: Pennsylvania State UniversityProposal Title: Anisotropic Thermal Transport in Fuel CellsAbstractThe proposal deals with the coupling between anisotropic thermal transport and water management in PEM fuel cell membrane systems. Water management is critical to the efficient operation of the fuel cell. The proposed research will include measurements of the anisotropic thermal conductivity of the gas diffusion layer and the electrolyte, as well as the gas and surface temperature of a 5 cm2 operating fuel cell. An analytical model will account for orthotropic thermal conductivity, as well as fluid mechanics, species transport, advection, and electrochemistry. The results will have impact on fundamental understanding of anisotropic thermal transport, will address the critical water management issues for PEM fuel cells, and will serve to expose mechanical engineering students to a technology area often considered to be outside the discipline.
