The invention relates to a propulsion system (150) comprising: a nacelle (202) having an air channel (208) in a longitudinal direction X; an electric motor (108), the output end of which drives the propeller (110); and a fuel cell (250) comprising: a core (251) located outside the air passage (208); open channels (253), each having an inlet opening and an outlet opening in the air channel (208), and for each open channel (253), the fuel cell includes a fuel chamber, an electrolyte between the open channel (253) and the fuel chamber, a cathode, and an anode, an inlet surface area of each open channel (253) is less than a surface area of an intermediate region between the inlet and the outlet, and a surface area of the outlet is less than a surface area of the intermediate region. Such a system may bring the fuel cell close to the electric motor, thereby reducing the length of the electrical conductor between the fuel cell and the electric motor, and thereby improving the operation of the fuel cell.
本发明涉及一种推进系统(150),该推进系统包括:短舱(202),其沿纵向方向X具有空气通道(208);电动马达(108),其输出端驱动螺旋桨(110);以及燃料电池(250),该燃料电池包括:位于空气通道(208)外部的芯(251);开放通道(253),每个开放通道具有在空气通道(208)中的入口开口和出口开口,并且对于每个开放通道(253),该燃料电池包括燃料室、在开放通道(253)与燃料室之间的电解质、阴极、和阳极,每个开放通道(253)的入口表面积小于在该入口与该出口之间的中间区域的表面积,该出口的表面积小于该中间区域的表面积。这种系统可以使燃料电池靠近电动马达,从而减小燃料电池和电动马达之间的电导体的长度,并由此改善燃料电池的运行。
