Abstract

A powerplant (20) for an aircraft includes a first turbine engine (22), a second turbine engine (24) and a fuel cell system (26). The second turbine engine (24) includes a second engine flowpath (100), a second engine compressor section (96), a second engine combustor section (97 and a second engine turbine section (98). The second engine flowpath (100) extends from a second engine flowpath inlet (114) to a second engine flowpath outlet (116). The second engine flowpath inlet (114) and the second engine flowpath outlet (116) are each fluidly coupled with a flowpath (80) of the first turbine engine (22). The fuel cell system (26) includes a fuel cell, a fuel circuit (142) and an air circuit (144). The fuel circuit (142) extends through the fuel cell and is fluidly coupled with and upstream of a first fuel injector in the second engine combustor section (97). The air circuit (144) extends through the fuel cell and is fluidly coupled with and downstream of a bleed (160) from the second engine flowpath (100).
