GAS TURBINE COMBUSTION SECTION HAVING AN INTEGRATED FUEL CELL ASSEMBLY

A combustion section (114) defines an axial direction, a radial direction, and a circumferential direction. The combustion section (114) includes a casing (400) that defines a diffusion chamber (406). A combustion liner (402) is disposed within the diffusion chamber (406) and defines a combustion chamber (404). The combustion liner (402) is spaced apart from the casing (400) such that a passageway (408) is defined between the combustion liner (402) and the casing (400). A fuel cell assembly (410) is disposed in the passageway (408). The fuel cell assembly (410) includes a fuel cell stack (415) having a plurality of fuel cells (416) each extending between an inlet end (418) and an outlet end (420). Each fuel cell of the plurality of fuel cells (416) includes an air channel (496) and a fuel channel (498) each fluidly coupled to the combustion chamber (404).
