PROBLEM TO BE SOLVED: To provide fuel cell-gas turbine power generating equipment which can appropriately control the air flow rate supplied to the fuel cell. SOLUTION: The equipment comprises a compressor 3 which compresses the air, a heat exchanging device which heats the air compressed at the compressor 3; a fuel cell which generates electric power with the cell reaction of supplied oxygen in the compressed air and the fuel via an electrolyte, when the compressed air heated by the heat exchanging device is supplied to an air pole and the fuel is supplied to a fuel pole; a combustor 8 to which exhaust air and exhanst fuel gas from the fuel cell is sent; a gas turbine 4 which is equipped coaxially with the compressor 3 and driven, when the combustion gas from the combustor 8 expands; a flow rate adjusting device which adjusts flow rate of the compressed air in the upstream of the heat exchanging device; and a cooling device which cools the exhaust fuel gas from the fuel cell.
