航空排放的增长速度比任何其他部门都快，它们有可能破坏通过减少其他经济领域的排放而取得的进展。基于氢和燃料电池的快速崛起的技术可以被开发出来，用于未来更换更电动或全电动飞机的机上电气系统。部署这些技术的主要优势是低排放和低噪音(这是在城市地区起降的通勤飞机的重要特征)。固体氧化物燃料电池系统由于其接受碳氢化合物和高能量密度燃料的能力，在一些航空应用中可能是有利的。此外，它们适合在热电组合配置下运行；它们从高温废气中回收热量，这些废气可以用来提供热负荷，从而减少飞机所需的电力。以燃料电池为动力的环保型城际飞机是欧盟委员会航空航天司选定的第六个框架方案项目，由意大利都灵理工大学牵头。该项目的目标之一是对不同类型的电动城际飞机进行可行性研究。在描述了电负载和非电负载的能耗，定义了三种不同类型客机的任务轮廓后，通过假设不同的系统结构，进行了基于固体氧化物燃料电池的能源系统的设计以及完整任务的仿真。模拟涉及电堆(电流和电流密度、电池和电堆电压等)。以及工厂的平衡(空压机功率、总烟囱功率、系统效率等)。并对所得结果进行了分析和讨论。
Aviation emissions are growing faster than any other sector and they risk undermining the progress achieved through emission cuts in other areas of the economy. Rapidly emerging hydrogen- and fuel-cell-based technologies could be developed for future replacement of onboard electrical systems in more-electric or all-electric aircraft. The primary advantages of deploying these technologies are low emissions and low noise (important features for commuter airplanes that take off and land in urban areas). Solid oxide fuel-cell systems could be advantageous for some aeronautical applications due to their capability of accepting hydrocarbons and high energy-density fuels. Moreover, they are suitable for operating in combined heat and power configurations; they recover heat from hightemperature exhaust gases, which could be used to supply thermal loads and thereby reduce the electric power requested by the aircraft. Environmentally Friendly Inter City Aircraft Powered by Fuel Cells is a Sixth Framework Programme project selected by the Aeronautics and Space division of the European Commission and led by the Politecnico di Torino in Turin, Italy.One of the objectives of the project is to carry out a feasibility study on different typologies of more-electric intercity aircraft. After the characterization of the power consumption of electrical and nonelectrical loads, and the definition of mission profiles for three different typologies of passenger aircraft, the design of the solid oxide fuel-cell-based energy system as well as the simulation of complete missions is performed by hypothesizing different system configurations. The simulations concern both the stack (current and current density, cell and stack voltage, etc.) and the balance of plant (air compressor power, gross stack power, system efficiency, etc.). Obtained results are analyzed and discussed
