Today's Paper is about #aeronautics and #fuelcell #systems for achieving #carbon_neutral #aviation. ✈🌍 𝙀𝙛𝙛𝙚𝙘𝙩𝙨 𝙤𝙣 𝙩𝙝𝙚 𝙙𝙚𝙨𝙞𝙜𝙣 𝙤𝙛 𝙖𝙚𝙧𝙤𝙣𝙖𝙪𝙩𝙞𝙘𝙖𝙡 𝙛𝙪𝙚𝙡 𝙘𝙚𝙡𝙡 𝙨𝙮𝙨𝙩𝙚𝙢𝙨 𝙗𝙮 𝙞𝙣𝙘𝙡𝙪𝙨𝙞𝙤𝙣 𝙤𝙛 𝙧𝙚𝙡𝙞𝙖𝙗𝙞𝙡𝙞𝙩𝙮 𝙧𝙚𝙦𝙪𝙞𝙧𝙚𝙢𝙚𝙣𝙩𝙨 To achieve carbon neutrality in commercial aviation, electric motors and systems combined with fuel cells powered by #green_hydrogen are promising solutions. This work applies reliability and safety engineering to the design process of aeronautical fuel cell systems, focusing on aspects of redundancy. The model is utilized to simulate failure scenarios for a central-monolithic fuel cell system designed for a regional aircraft. This simulation aims to identify effective strategies for incorporating redundancy measures.

🤓 Curious about #Modelling of #electrolyser and #fuelcells? Our latest paper in Elsevier - Electrochimica Acta, volume 495, 144482: ▶https://lnkd.in/d5YGq2aq 𝙉𝙀𝙊𝙋𝘼𝙍𝘿-𝙓: 𝙈𝙪𝙡𝙩𝙞𝙙𝙞𝙢𝙚𝙣𝙨𝙞𝙤𝙣𝙖𝙡 𝙝𝙞𝙜𝙝𝙡𝙮 𝙚𝙛𝙛𝙞𝙘𝙞𝙚𝙣𝙩 𝙖𝙣𝙙 𝙨𝙘𝙖𝙡𝙖𝙗𝙡𝙚 𝙢𝙤𝙙𝙪𝙡𝙖𝙧 𝙛𝙧𝙖𝙢𝙚𝙬𝙤𝙧𝙠 𝙛𝙤𝙧 𝙢𝙤𝙙𝙚𝙡𝙡𝙞𝙣𝙜 𝙤𝙛 𝙚𝙡𝙚𝙘𝙩𝙧𝙤𝙡𝙮𝙨𝙚𝙧𝙨 𝙖𝙣𝙙 𝙛𝙪𝙚𝙡 𝙘𝙚𝙡𝙡𝙨 The framework features a #modular and #flexible #structure, which enables wide applicability for a variety of fuel cell and electrolyser technologies. It is multi-threaded for shared memory architectures. The generic approach for discretisation allows efficient distribution of tasks between processing cores. The physical model is clearly separated from discretisation and the linear solver. This simplifies the model development and provides high flexibility with respect to the discretisation methods, linear solvers, as well as the dimensionality of the application. Irregular grids and complex geometries can be realised through generic mapping of coordinate systems. Single cell models can be easily scaled to short stacks. The framework features are demonstrated with realistic #PEMFC and #SOEC models. Whilst the PEMFC example focuses on the differences between different model dimensions and different boundary conditions, the SOEC example demonstrates the extension of a transient single cell model to a transient short stack model. The performance scalability with the number of CPUs is demonstrated.
