FUEL BATTERY SET FOR AIRCRAFT PROPULSION SYSTEM

Abstract

FUEL CELL ASSEMBLY FOR AIRCRAFT PROPULSION SYSTEM The invention provides an assembly (100) for an aircraft propulsion system (50) having a channel (52) in which an airflow (10) passes. The assembly (100) is disposed in the airflow (10) and comprises a compressor (102), a turbine (104) downstream of the compressor (102), a secondary shaft (106) having a secondary longitudinal axis (x) and fixed between the compressor (102) and the turbine (104), and at least two fuel cells (108a-b) between the compressor (102) and the turbine (104), one behind the other along the secondary longitudinal axis (x) in the airflow (10) and where each fuel cell (108a-b) is supplied with dihydrogen. With this arrangement, the oxygen is heated as it passes through the fuel cells (108a-b) before reaching the turbine (104). Fig. 2

Claims

8. Propulsion system (50) according to claim 7, characterized in that the secondary longitudinal axis (x) and the main longitudinal axis (X) are coaxial and in that the secondary shaft (106) is mounted movable around the main shaft (58).

9. Aircraft (1) comprising at least one propulsion system (50) according to one of claims 7 or 8. [Fig. 1] 108a
