Summary:

Aviation accounts for approximately 2.4% of global annual carbon emissions, and with an expected passenger traffic growth of 3.6–3.8% per year, CO₂ emissions could double by 2050 without additional mitigation measures. To address this challenge, initiatives such as the EU Flightpath 2050 project promote carbon-free aviation through alternative energy solutions. Among these, sustainable aviation fuel and hydrogen are the most viable options. Liquid hydrogen (LH₂) is particularly attractive due to its high gravimetric energy density, nearly three times that of conventional jet fuel. When used in fuel cell–based electric aircraft, hydrogen offers higher efficiency, quieter operation, and eliminates emissions such as CO₂, NOₓ, and SO₂. As a result, major aerospace companies are exploring fully electric and hybrid-electric aircraft concepts. This work focuses on a fully electric aircraft powered by proton exchange membrane fuel cells (PEMFCs).High power requirements significantly increase system weight, especially hydrogen storage. Therefore, lightweight and efficient powertrain components are essential. Superconducting technologies offer reduced weight, higher efficiency, and compact power transmission, making them promising for aviation electrification. This study presents a MATLAB/Simulink model of a superconducting fuel cell–based electric aircraft powertrain, enabling system-level simulations under various flight scenarios. The proposed fuel cell model captures nonlinear voltage–current behavior and accurately represents resistive, inductive, or combined transient dynamics.
