Classification: CPC F | IPC F

Claim 19:
20. An assembly for late lean injection of fuel into a gas turbine combustor, comprising:
a fuel and air premixing device configured to alter a fuel composition;
a fuel and air conditioning device configured to further alter the fuel composition and generate electrical power, the fuel and air conditioning device including a first fuel cell stack having a first channel to receive a first portion of air and a first portion of the fuel positioned upstream of a second fuel cell stack having a second channel to receive a second portion of air and a second portion of the fuel, wherein the first fuel cell stack is separated by a gap from the second fuel cell stack, the gap between the first fuel cell stack and the second fuel cell stack is different than a gap between adjacent fuel cells within each of the plurality of fuel cell stacks; and
a controller configured to control the fuel and air premixing device and the fuel and air conditioning device to achieve a desired gas composition distribution in the gas turbine combustor along an axial direction of the gas turbine combustor.
