The invention has an object to provide a fuel cell power generating system with a simple system configuration, excellent in reliability and cooling ability, and permitting high power density operation. At least two internal reforming type fuel cell apparatuses are connected in series in the flow direction of a fuel gas via a methanator to ensure a flow rate of the fuel gas supplied to each fuel cell apparatus, sufficient to ensure cooling of the cells, thus eliminating the necessity of a high-temperature circulating blower or a high-temperature piping for a fuel gas, which are both expensive. Furthermore, it is possible to use the fuel gas repeatedly as a cooling gas under the effect of the methanator. It is also possible to largely improve the cooling performance of cells through internal reforming cooling, without the use of an expensive fuel gas circulating blower.
