BREEZE! –电池电动车用燃料电池增程器：零排放

纯电池电动车能够满足日常驾驶的基本需求，但是行车里程是受电池容量限制的，扩充电池蓄电意味着延长充电时间。在2016年11月份举行的第六届中国汽车和发动机技术年会上，亚琛工业大学内燃机研究所（VKA）展示了“BREEZE!”项目。这是个公共资金扶持的开发项目，采用氢燃料电池系统提高电池续程并实现零排放。最终，此燃料电池增程器被集成到，由FEV有限‍公司开发的菲亚特500电池电动车上，此开发项目即公共资金扶持的“智能车”项目。

Pure battery electric vehicles are able to cover most of the daily driving distances but driving range is limited due to battery capacity and doubling battery capacity means doubling time for a full recharge. The Institute for Combustion Engines (VKA) at RWTH Aachen University presented the project "BREEZE!" during the 6th China Automobile and Engine Technology in November 2016. The scope of the public-funded project "BREEZE!"is to extend zero emission range of battery electric vehicles by using a fuel cell system working with hydrogen. At the end of the project this fuel cell range extender was integrated into a battery electric Fiat 500 developed by FEV GmbH in the public-funded project "Smart-Wheels".

自2011年以来，项目组从零开始研发整个燃料电池系统。以电池组件的材料认证为出发点，将适用于增程器的电池组件双极板和薄膜电解质以客户需求为核心进行了系统地开发。在项目中，内燃机研究所（VKA）定义了燃料电池辅助件集成的边界条件。在此基础上，开发了系统控制软件和整车集成。对电池堆栈的机械布局进行了彻底修改，以满足车辆应用的要求。原型车所需的尺寸要求使整个系统非常紧凑。为达到此目的，内燃机研究所（VKA）将主要燃料电池辅助件集成到一块开发的新板上。

Since 2011, the project consortium has developed the entire fuel cell system starting from scratch. Starting with material qualification for the cell components bipolar plate and membrane electrolyte assembly an entirely new cell customized for its application in a fuel cell range extender was developed.In close cooperation with this task, the Institute for Combustion Engines (VKA)defined the balance of plant components which set the boundaries for theo peration strategy. Based on that, the control software of the system and its integration into the vehicle was developed.  The mechanical layout of the stack was completely revised to come up to the requirements derived from the application in a vehicle. The required package size of the base vehicle constrains the entire system to be very compact. For this purpose, the Institute for Combustion Engines (VKA) developed a new endplate concept integrating the majority of the balance of plant components.

将燃料电池系统集成到整车中，需要对原型车和电池系统进行多种调整。在车的前端，散热片必须被替换成，用于燃料电池冷却回路和初始动力总成回路的专用散热片。这是在有限空间中，采用三明治式冷却器的概念实现的。后座椅下集成氢高压储罐要求对车的后部进行一系列调整。在发生起火或减压器发生故障时，保证将氢气从储罐安全地通过独立的通风管路排出车顶。最后，主底盘梁被加固，以承载燃料电池承轴额外的负荷。成功完成整车集成，包括硬件集成和布线。

The integration of the fuel cell system into the vehicle required several adaptations of the base vehicle to the fuel cell system. In the vehicles front-end, the radiator had to be exchanged for a special fuel cell radiator serving the fuel cell coolant circuit and the initial powertrain circuit separately. This was realized by a sandwich cooler concept in the limited space. The integration of the hydrogen high-pressure tank under the rear seats of the vehicle required a few modifications of the vehicle’s back end. To blow off the hydrogen from the tank safely in case of fire or a malfunction of the pressure reducer, it is routed through separate vent lines to the vehicle's roof. Finally, the main chassis beams were reinforce to carry the extra load of the fuel cell bearings. The vehicle integration was successfully completed including hardware integration and wiring harness.
