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

这项建议是早些时候NSERC与Ballard合作的CRD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”。它还打算完成与Ballard合作的APC项目产生的未完成任务，该项目将于2014年6月结束。在这方面，NSERC CRD建议的目标是通过为PEMFC电堆系统设计基于模型的控制策略和车载诊断系统来提高Ballard的燃料电池、燃料输送系统(FDS)的性能。 在这份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，为公交应用中使用的燃料电池(FC)模块提供最佳的FDS控制。在所提出的方法中，考虑到FC电堆或系统部件中的转移和外部燃料泄漏检测，将开发一种主动燃料供应控制。该CRD将通过开发运行中的燃料供应控制模型来帮助实施该燃料输送系统。该项目的这一方面(即建模和改进燃料供应控制)是通过确保在整个寿命内提供足够的燃料来延长燃料电池寿命的有效方法，也是通过监测运行中的燃料使用来提高这些系统的安全性、可靠性和耐用性的有效方法。

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.
