Maintenance assessment of fuel cell systems for regional aircraft
本研究采用以可靠性为中心的维护方法和MSG-3框架，评估低温质子交换膜燃料电池和固体氧化物燃料电池系统的维护范围与成本，为支线飞机选择最适合的燃料电池系统提供依据。
With the EU’s Green Deal Climate Act, airlines encounter the challenge of reducing their impact by operating in a climate-neutral manner. Fuel cell technologies, including Low Temperature Proton Exchange Membrane Fuel Cells and Solid Oxide Fuel Cells, are suitable candidates for this endeavour. However, there is uncertainty surrounding the maintenance scope and corresponding costs of novel systems such as fuel cells, that is leading to reluctance within the industry to implement these technologies. This study addresses this research gap by assessing the fuel cell systems using the Reliability Centered Maintenance approach and the MSG-3 framework. For this purpose, task intervals are determined based on statistical reliability values from literature and data from legacy aircraft. As a final step, the scheduled maintenance scope is derived, accounting for the required maintenance tasks, corresponding intervals, and parts of the labor and material scope. The aim of this comparative study is to identify the fuel cell system best suited for regional aircraft operations based on its maintenance characteristics. This enables us to provide designers and researchers with valuable insights to support the development of technically feasible fuel cell systems for the aviation industry.
