Hydrogen fuel cells are gaining significant momentum worldwide due to the increasingly urgent need for zero-emission transportation systems across all sectors. Large-scale adoption of fuel cell electric vehicles, however, still requires significant cost reductions and durability improvements, in particular for heavy duty vehicles. The ionomer membrane that separates the two fuel cell electrodes is at the epicentre of this dilemma, being a costly component at scale, which is also susceptible to premature failure. There are also concerns about the environmental impacts of the fluorinated membranes that are typically used in this application, as toxic, bio-accumulating fluorine waste may adversely affect human health and natural ecosystems. A promising route to achieving cost reduction is therefore to investigate low-cost, fluorine-free membranes to replace the conventional materials used in fuel cells. However, past attempts to introduce alternative membranes have failed due to poor stability and durability in the fuel cell environment. The overarching goal of the proposed research is to address and overcome the present stability and durability impediments of emerging, fluorine-free membranes for polymer electrolyte fuel cell applications. Fuel cell durability is considered the last remaining research frontier for these breakthrough materials and will be addressed in this project using an in-depth scientific approach, targeting to unlock broad societal adoption and use of the technology. The project will form a new university-industry research partnership between Simon Fraser University (SFU) Fuel Cell Research Lab (FCReL) and Ionomr Innovations, covering the required expertise, facilities, and knowledge translation to generate transformative results and outcomes. Specifically, this partnership will merge FCReL's vast expertise and research tools on fuel cell durability with Ionomr's emerging, high-performing hydrocarbon ionomer materials and related expertise and technical knowledge.

氢燃料电池在全球范围内的巨大动量由于越来越迫切需要所有部门的零发射运输系统。但是，大规模采用燃料电池电动汽车仍然需要大幅降低成本和耐用性，尤其是重型车辆。将两个燃料电池电极分开的离子膜处于这一困境的中心，是昂贵的大小成分，这也容易受到过早故障的影响。对于本应用程序中通常使用的氟化膜的环境影响也令人担忧，因为有毒，生物累积的氟废物可能会对人类健康和自然生态系统产生不利影响。因此，实现成本降低的有希望的途径是研究低成本的无氟膜，以取代燃料电池中使用的常规材料。但是，由于燃料电池环境中的稳定性和耐用性较差，过去试图引入替代膜的尝试失败了。拟议的研究的总体目标是解决和克服用于聚合物电解质燃料电池应用的新兴，无氟膜的当前稳定性和耐用性障碍。燃料电池的耐久性被认为是这些突破性材料的最后剩下的研究前沿，该研究将在该项目中使用深入的科学方法来解决，旨在解锁广泛的社会采用和对技术的使用。该项目将在Simon Fraser大学（SFU）燃料电池研究实验室（FCREL）和IONOMR创新之间建立新的大学行业研究合作伙伴关系，涵盖了所需的专业知识，设施和知识翻译，以产生变革性的结果和成果。具体而言，这种合作伙伴关系将使FCREL的庞大专业知识和研究工具与Ionomr的新兴，高性能的碳氢离子材料以及相关的专业知识和技术知识合并。
