Claim 6:
7. A turbomachine comprising:
a compressor section, a combustion section, and a turbine section arranged in serial flow order, 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 stack having a plurality of fuel cells each extending between an inlet end and an outlet end, each fuel cell of the plurality of fuel cells comprising an air channel and a fuel channel each fluidly coupled to the combustion chamber,
wherein the fuel channel of two or more fuel cells in the plurality of fuel cells each extend from a respective fuel inlet to a fuel plenum, the fuel plenum extending to a common fuel outlet in fluid communication with the combustion chamber,
wherein each fuel cell of the plurality of fuel cells comprises an air channel at least partially defined by a cathode, and wherein the air channel of two or more fuel cells in the plurality of fuel cells each extend from a respective air inlet to an air plenum, the air plenum extending to a common air outlet in fluid communication with the combustion chamber,
wherein the common fuel outlet is disposed at one of a forward end or an aft end of the fuel cell stack, and
wherein the common air outlet is disposed at the other of the forward end or the aft end of the fuel cell stack.
