1. A method of operating a propulsion system having a gas turbine engine and a fuel cell assembly, the fuel cell assembly comprising a fuel cell, the method comprising:
receiving gas composition data of output products from the fuel cell; and
controlling operation of the fuel cell assembly, the gas turbine engine, or both in response to the received gas composition data of the output products from the fuel cell;
wherein receiving the gas composition data comprises receiving the gas composition data from a gas sensor, and wherein controlling operation of the fuel cell assembly, the gas turbine engine, or both in response to the received gas composition data comprises:
using a model-based control to control operation of the fuel cell assembly, the gas turbine engine, or both, and wherein using the model-based control comprises:
determining estimated gas composition data using a model; and
determining actual gas composition data based on the determined estimated gas composition data and the received gas composition data using a fusion filter.
