The propulsion system of the aircraft comprises a fuel cell

摘要

The propulsion system of the aircraft comprises a fuel cellThe invention relates to a propulsion system (150), which comprises a nacelle (202) with an air passage (208) along the longitudinal X direction, an electric motor (108), and an output driving propeller (110),And a fuel cell (250) having a core (251) protruding from an air passage (208),Opening channels (253), wherein each channel has an open inlet and an open outlet in the air channel (208),For each open channel (253),Electrolyte, cathode and anode between fuel chamber, open channel (253) and fuel chamber, wherein each open channel (253) has an inlet surface smaller than the surface of the middle area between inlet and outlet, The exit area is smaller than the middle area.This system makes the fuel cell close to the motor, thus reducing the length between the conductors and improving the performance of the fuel cell.Figure 2
