Compact, efficient, low-cost turbomachine compressor for automotive fuel cell systems

该项目旨在为燃料电池行业提供压缩机。这需要空气动力学，电气和机械创新，但如果成功，它将为汽车燃料电池系统提供最低成本，紧凑，高效和可扩展的压缩机。该项目将使用一个铝制的压缩机，具有汽车制造公差，直接耦合到一个可变的高速电机，没有传输。这代表了罗茨和螺杆式压缩机的一个阶跃变化。该项目还必须设计压缩机，以科普广泛的流量图，以适应燃料电池的要求，以及运行没有油污染的燃料电池。此外，电动机必须耐受高度可变的输入电压，反映燃料电池电压的变化，使得电动机可以直接从燃料电池的端子运行，而不需要燃料电池的输出DC/DC转换器上的附加负载。该项目将由Aeristech领导，Aeristech将其专有和专利技术应用于这一独特的、对油不利的、可变电压应用中。帝国理工学院将提供一种压缩机设计，能够在一定范围的质量流量恒定升压。Intelligent Energy将把电动助力器集成到他们的燃料电池和燃料电池控制器中，然后进行性能测试。该项目将以一个在燃料电池上工作的压缩机结束。项目完成后，合作伙伴将继续完善、改进和利用该系统。

This project aims to make turbomachine compressors available to the fuel cell industry. This requires aerodynamic, electrical, and mechanical innovations, but if successful it will provide the most low-cost, compact, efficient, and scalable compressor for automotive fuel cell systems. The project will use an aluminium, turbomachine-type compressor with volume automotive manufacturing tolerances, direct-coupled to a variable high-speed motor with no transmission. This represents a step-change from roots and screw-type compressors. The project must also design the compressor to cope with a wide flow map to suit fuel cell requirements, as well as to operate without oil contamination to the fuel cell. Additionally, the electric motor must tolerate highly variable input voltage, reflecting the variations in fuel cell voltage, so that the motor can run directly from the fuel cell's terminals without the need for an additional load on the fuel cell's output DC/DC converter. The project will be led by Aeristech who will apply its proprietary and patented technology in variable high-speed motors for turbomachine direct drive to this unique, oil-adverse, variable-voltage application. Imperial College will provide a compressor design capable of constant boost across a range of mass flows. Intelligent Energy will integrate the electric booster into their fuel cell and fuel cell controller, then carry out performance tests. The project will conclude with a turbomachine compressor working on a fuel cell. Following completion of the project, the system will continue to be refined, improved, and exploited by the partners.
