Heavy duty fuel cell module diagnostics, control & safety system improvements

该提案是早期NSERC CRD与Ballard合作的项目的延伸，该项目名为“重型燃料电池模块诊断，控制和安全系统改进”。“它还打算结束与巴拉德的APC项目所产生的未完成的任务，该项目将于2014年6月结束。在这方面，这个NSERC CRD提案的目标是通过设计基于模型的控制策略和PEMFC堆系统的车载诊断系统来改善巴拉德的燃料电池、燃料输送系统（FDS）的性能。 在该CRD提案中，Ballard正在寻求为燃料输送系统（FDS）设计和优化一个基于模型的平台，该平台包含一个诊断系统，为公交车应用中使用的燃料电池（FC）模块提供最佳FDS控制。在所提出的方法中，主动燃料供应控制将开发考虑转移和外部燃料泄漏检测在FC堆栈或系统组件。该CRD将通过开发运行中的燃料供应控制模型来协助实施该燃料输送系统。项目的这一方面（即，建模和改进的燃料供应控制）是一种有效的方式，通过确保在整个寿命期间足够的燃料输送来延长燃料电池的寿命，并且还通过监视操作中的燃料使用来改进这些系统的安全性、可靠性和耐久性。

This proposal is an extension of an earlier NSERC CRD project with Ballard, titled "Heavy Duty Fuel Cell Module Diagnostics, Control & Safety System Improvements." It is also intended to wrap up the unfinished tasks stemming from an APC project with Ballard that will end in June 2014. In this regard, the goal of this NSERC CRD proposal is to improve Ballard's fuel cell, fuel delivery system (FDS) performance by designing a model-based control strategy and on-board diagnostics system for a PEMFC stack system. In this CRD proposal, Ballard is seeking to design and optimize a model-based platform for a fuel delivery system (FDS) incorporating a diagnostic system to provide optimal FDS control for fuel cell (FC) modules used in transit bus applications. In the proposed approach, an active fuel supply control will be developed considering transfer and external fuel leak detection in the FC stack or system components. This CRD will assist in implementing this fuel delivery system by developing models for fuel supply control in operation. This aspect of the project (i.e., modeling and improved fuel supply control ) is an effective way to extend the lifetime of the fuel cells by ensuring adequate fuel delivery over life, and also to improve the safety, reliability and durability of these systems by monitoring fuel usage in operation.
