Anti-stall system with a fuel cell

An anti-stall system for an aircraft, the anti-stall system comprising:

• a propulsion system including, in serial flow relationship, a low-pressure compressor, a high-pressure compressor, and a combustion section, wherein the propulsion system further comprises a secondary compressor, a fuel cell assembly, an electric bus, an electric machine, and at least one shaft, and wherein the combustion section comprises a combustor including an inner liner, an outer liner, and a combustion chamber defined therebetween, wherein the secondary compressor is fluidly coupled to the low-pressure compressor via a first bleed flow path to receive a first bleed flow from the low-pressure compressor, wherein the secondary compressor is fluidly coupled to the high-pressure compressor via a second bleed flow path to receive a second bleed flow from the high-pressure compressor, wherein the second compressor is in airflow communication with the fuel cell assembly to provide at least one of the first bleed flow or the second bleed flow to the fuel cell assembly, wherein the fuel cell assembly is integrated with the inner liner or the outer liner and is in fluid communication with the combustion chamber, and wherein the electric bus is electrically coupled to the fuel cell assembly and the electric machine;
• a sensor configured to sense data indicative of an operating parameter indicative of a compressor stall condition of at least one of the low-pressure compressor or the high-pressure compressor;
• and
• a controller electronically coupled to the sensor, wherein the controller is configured to:
• receive the data indicative of the operating parameter indicative of the compressor stall condition, wherein receiving the data indicative of the operating parameter comprises receiving data indicative of one or more of a flame in the combustor, rotational speed of the at least one shaft, or a combustion engine load;
• and
• execute an anti-stall action responsive to the data indicative of the operating parameter indicative of the compressor stall condition if the operating parameter has achieved a compression stall condition threshold, wherein executing the anti-stall action includes increasing or decreasing at least one fuel cell parameter of the fuel cell assembly.
