Claim 12:
13. A method of operating a propulsion system, the propulsion system comprising a modular fuel cell assembly and a gas turbine engine, the method comprising:
providing output products from a first fuel cell of a first fuel cell string of the modular fuel cell assembly and from a second fuel cell of a second fuel cell string of the modular fuel cell assembly to a combustor of a combustion section of the gas turbine engine;
receiving gas composition data of a first fluid flow through the first fuel cell string and of a second fluid flow through the second fuel cell string;
modifying an operating parameter of the first fuel cell string, of the second fuel cell string, or both in response to the received gas composition data; and
receiving operational data of the modular fuel cell assembly, of the gas turbine engine, of an aircraft including the modular fuel cell assembly and the gas turbine engine, or a combination thereof, and wherein modifying the operating parameter comprises modifying the operating parameter of the first fuel cell string, of the second fuel cell string, or both in response to the received gas composition data and the received operational data,
wherein the operational data comprises: a health indicator of the fuel cell assembly, the gas turbine engine, or both; a flight schedule of an aircraft including the fuel cell assembly and gas turbine engine; a maintenance schedule of the aircraft or a combination thereof, and wherein the health indicator of the fuel cell assembly, the gas turbine engine, or both comprises accumulated health information.
