1. A combustion section defining an axial direction, a radial direction, and a circumferential direction, the combustion section comprising:
a casing defining a diffusion chamber;
a combustion liner disposed within the diffusion chamber and defining a combustion chamber, the combustion liner spaced apart from the casing such that a passageway is defined between the combustion liner and the casing; and
a fuel cell assembly disposed in the passageway, the fuel cell assembly comprising a fuel cell extending between an inlet end and an outlet end, wherein the inlet end receives a flow of air and fuel and the outlet end provides output products to the combustion chamber, the fuel cell extending at an angle between the inlet end and the outlet end relative to a radial projection line, wherein the combustion section defines a radial gap length between the casing and the combustion liner at a mounting location of the fuel cell assembly, wherein the fuel cell defines a fuel cell length, and wherein the fuel cell length is longer than the radial gap length, and wherein the inlet end is disposed fully within and in fluid communication with the passageway.
