项目摘要

Hydrogen is a clean source of energy with zero Green House Gas emissions, and a very efficient method of**obtaining power from hydrogen is by using fuel cells, which generate electricity by an electrochemical reaction**in which oxygen and hydrogen combine to form water and hence there are no harmful emissions. Hydrogenics**Corporation, a Canadian company, is one of the market leaders in providing hydrogen fuel cells and**electrolyzers, all over the world. A major component of fuel cells, the bipolar plates cost about one third of the**total cost of the fuel cells. Therefore, development of bipolar plates that have better properties and can be**produced more economically will be of great value in the development of this technology. In 2017,**Hydrogenics Corporation collaborated with the Principal Investigator (PI) Prof. Ghaus Rizvi of the University**of Ontario Institute of Technology (UOIT) to develop a compounding process to produce**polypropylene-graphite composites for bipolar plates. The composite specimen with various compositions were**produced and tested for electrical and mechanical properties. A number of these had the desired characteristics**and can be used for fabrication of bipolar plates. Hydrogenics Corporation is now interested in development of**a process for production of actual bipolar plates using these composites. Hence, this Engage Plus grant will**focus on the design and development of a sheet extrusion setup for Bipolar plates through a sheet die followed**by compression of the sheet into bipolar plates. The composite, which is polymer loaded with 70 to 80 wt % of**particulate graphite and other solid conductive materials, has complex flow behavior. The experimental study**will involve composites' compounding, composites' sheets and bipolar plates processing as well as material**rheological characterization for proper sheet die design. Successful completion of this project will lead great**economic windfall for the company as well as for Canadian economy.

氢是一种清洁的能源，具有零温室气体的排放，并且通过使用燃料电池是一种非常有效的**从氢中获取功率的方法，该方法通过电化学反应产生电力**，其中氧气和氢结合形成水以形成水因此没有有害的排放。加拿大公司氢化公司**公司是全世界提供氢燃料电池和**电解质的市场领导者之一。双极板是燃料电池的主要组成部分，约占燃料电池总成本的三分之一。因此，开发具有更好性能并且可以在经济上更具经济性能的双极板块在这项技术的开发中具有巨大的价值。 2017年，**氢化公司与安大略省理工学院（UOIT）的大学（PI）的Ghaus Rizvi教授合作，开发了一个复合过程，以生产**多丙烯 - 磷脂复合材料，用于双极板。产生了具有各种组合物的复合样品，并测试了电气和机械性能。其中许多具有所需的特性**，可用于制造双极板。氢化公司现在对使用这些复合材料生产实际双极板的过程感兴趣。因此，这项参与加赠款将**将重点放在通过纸模层的双极板的设计和开发上，然后**将纸压缩到双极板中。该复合材料的聚合物装有70至80 wt％**颗粒石墨和其他固体导电材料，具有复杂的流动行为。实验研究**将涉及复合材料的复合材料，复合材料的表和躁郁症板的加工以及材料**流变特征，以进行适当的薄板设计。该项目的成功完成将为公司和加拿大经济带来巨大的经济意外收获。
