The research objective of this BRIGE award is to understand the permeability of gases through a non-traditional woven structure subjected to non-uniform porosity. This research will provide a fundamental understanding of the mechanisms required to develop a functional graduated material with controlled dimensionality, for use in renewable energy devices. A successful result of this investigation will be a methodology to develop functional materials with unique dimensionality, such that the resistance of a gas to flow may be controlled. Numerical modeling will be conducted to predict how the gases will flow through the graduated medium and to aid with defining the optimal design. Performance analysis will be conducted to evaluate the properties of the woven structure in a functional system. If successful, the results of this research will lead to a fundamental understanding of gas permeability through a controlled graduated woven structure with non-uniform porosity, which is not well understood. Nontraditional porous media for varying applications have emerged, and such an understanding may impact the design of these systems according to the resulting properties that are desired. The proposed work will contribute to this objective by studying the dimensionality of a woven carbon cloth, which is commonly used in polymer electrolyte membrane fuel cells (PEMFCs). This work will identify key parameters that influence the performance of such systems, leading to innovative stack designs that fundamentally challenge conventional fuel cell configurations and their effectiveness. Coordinated with the technical objective, the outreach goal of implementing a collaborative program coined ELECTRoDE (Educators Leading Energy Conservation and Training Researchers of Diverse Ethnicities) will be employed.

该BRIGE奖的研究目标是了解气体通过非传统编织结构的渗透性，该结构具有不均匀的孔隙率。这项研究将提供一个基本的了解所需的机制，以开发一个功能性的渐变材料与控制的维度，用于可再生能源设备。这项研究的成功结果将是开发具有独特维度的功能材料的方法，以便可以控制气体流动的阻力。将进行数值建模，以预测气体将如何流过分级介质，并帮助确定最佳设计。 将进行性能分析，以评估功能系统中编织结构的性能。 如果成功，这项研究的结果将使人们对具有不均匀孔隙率的受控分级编织结构的气体渗透性有一个基本的了解，而这种结构目前还没有得到很好的理解。已经出现了用于不同应用的非传统多孔介质，并且这样的理解可能会根据所期望的所得性质影响这些系统的设计。拟议的工作将有助于这一目标，通过研究编织碳布，这是常用的聚合物电解质膜燃料电池（PEMFC）的维数。 这项工作将确定影响此类系统性能的关键参数，从而产生创新的电池堆设计，从根本上挑战传统的燃料电池配置及其有效性。 与技术目标相协调，将采用实施一项名为ELECTRODE（教育工作者领导节能和培训不同种族的研究人员）的合作计划的外联目标。
