By 2050, the Committee on Climate Change has forecast that aviation could be the single largest contributor to UK emissions. Globally, it is predicted that aviation will contribute over 22% of all transport CO2 emissions by the same date. This trend is being driven by rapid expansion in passenger numbers, coupled with a lack of technological solutions to facilitate a move away from fossil fuels. Though COVID-19 reduced emissions in the short-term, the industry is still projected to miss its 2050 targets by an estimated 800 -- 1,400 million tons of CO2\.The most promising solution to this growing crisis is the electrification of flight. For short-to-medium haul flights there is an opportunity to develop electrified powertrains for aircraft on a timescale that could have a significant impact in reducing emissions. A key enabling technology for such powertrains will be high-power density PEM fuel cell systems. Compared to all-battery powertrains, utilising fuel cells would allow for increased flight range, heavier payloads, and quicker turn-around times. However, the power densities of current systems derived from the automotive industry are too low to make wide-scale adoption in aviation feasible.One means of increasing the power density of a fuel cell system is to reduce its mass. Approximately 40-50% of the mass of a PEM fuel cell system comes from the stack -- the part of the device responsible for converting the chemical potential energy of the fuel into electrical energy. One technology that offers unique opportunities to lightweight stack components is additive manufacturing.This project will exploit recent advances made at the MTC in producing aluminium parts from Powder Bed Fusion -- Laser Based (PBF-LB) to make a lightweight PEM fuel cell stack for aviation applications. Light-weighting will be achieved not only through exploiting the additive process to make optimised topologies, but by incorporating multi-functionality into components as well. The target will be to increase stack power density by at least 10% and reduce the overall number of components in the system.

气候变化委员会预测，到2050年，航空业可能成为英国排放量的最大贡献者。在全球范围内，预计到同一日期，航空业将占所有运输行业二氧化碳排放量的22%以上。这一趋势的推动因素是乘客数量的快速增长，加上缺乏技术解决方案来推动人们放弃化石燃料。尽管新冠肺炎在短期内减少了排放，但预计该行业仍将无法实现2050年的目标，二氧化碳排放量估计将达到8-14亿吨。解决这场日益严重的危机最有希望的解决方案是飞行电气化。对于中短途飞行，有机会为飞机开发电动动力总成，其时间表可能对减少排放产生重大影响。这种动力总成的关键使能技术将是高功率密度的质子交换膜燃料电池系统。与纯电池动力系统相比，使用燃料电池将允许增加飞行距离、更重的有效载荷和更快的周转时间。然而，当前源自汽车工业的系统的功率密度太低，不能在航空上广泛采用。提高燃料电池系统功率密度的方法之一是降低其质量。PEM燃料电池系统大约40%-50%的质量来自电堆--负责将燃料的化学势能转化为电能的装置部件。一项为轻质堆叠组件提供独特机会的技术是添加剂制造。该项目将利用MTC最近取得的进展，利用粉末床熔化-激光(PBF-LB)生产铝部件，以制造用于航空应用的轻型PEM燃料电池堆栈。轻量化将不仅通过利用添加过程来制造优化的拓扑结构来实现，还将通过将多功能整合到组件中来实现。目标是将堆叠功率密度提高至少10%，并减少系统中的组件总数。
