Heavy-Duty Fuel Cell System Optimization in a Hybrid Fuel Cell Powertrain

该提案是现有的NSERC Engage项目的扩展，该项目名为“重型燃料电池巴士混合动力测试台”。本项目的主要目标是建立一个重型混合动力系统的优化设计框架，将燃料电池的耐久性、动力性和效率纳入设计中，并建立一个硬件平台，用于研究先进的运行方案和能量管理方法的设计和开发。在这个CRD提案中，巴拉德正在寻求开发一个设计框架，使燃料电池的性能和耐久性在各种操作条件下的表征。该框架优化了燃料电池和蓄电池的尺寸，以实现最小的氢气消耗以及动力总成的成本。系统级的功率和能量管理控制器将被设计为最小化燃料电池的压力，并最大限度地提高其寿命。该CRD将通过开发组件模型和尺寸优化算法，以及实际实施混合燃料电池动力系统的功率转换器和控制方案，协助实施设计框架。通过最小化电压和动态应力，优化组件尺寸和能量管理方案是延长燃料电池寿命的最有效方法。

This proposal is an extension of an existing NSERC Engage project with Ballard, titled "Hybrid PowertrainTest Bed for Heavy-Duty Fuel Cell Bus". The proposed project is mainly aimed at developing an optimaldesign framework for the heavy-duty hybrid powertrain by incorporating fuel cell durability, dynamics, andefficiency into the design, and to build a hardware platform for research on design and development ofadvanced operation schemes and energy management methods. In this CRD proposal, Ballard is seeking todevelop a design framework which enables the characterization of fuel cell performance and durability undervarious operating conditions. The proposed framework optimizes the sizes of the fuel cell and the battery toachieve minimum hydrogen consumption as well as the cost of the powertrain. System-level controller forpower and energy management will be designed to minimize stressors on the fuel cell and maximize itslifetime. This CRD will assist in implementing the design framework by developing component models andsizing optimization algorithms, and physically implementing power converters and control schemes for thehybrid fuel cell powertrain. The optimum sizing of components and energy management scheme is the mosteffective way to extend the lifetime of the fuel cell by minimizing voltage and dynamic stressors.
