PURPOSE:To improve the generation characteristic of a fuel-cell power generating system, in which a cell body is constituted by electrically connecting plural fuel cell stacks in parallel, by preventing any unbalance in the gas flow by connecting at least one of a supply part and an exhaust part for each of fuel gas and oxidant gas. CONSTITUTION:A fuel body is constituted of parallel connected fuel cell stacks 14A-14E. An oxidant gas supply part is constituted of parallel connected fuel cell stacks 14A-14E. An oxidant gas supply part is constituted of the flow of air connecting the compressor 18A of a turbine compressor 18, an air supply tube 17 and the cell body in that order. An oxidant gas exhaust part is constituted of the flow of air connecting the cell body, an air exhaust tube 20, a mixer 21 and the turbine 18B of the turbine compressor 18 in that order. A fuel gas supply part is constituted of the flow of fuel gas connecting the catalyst 26A of a reformer 26, a fuel gas supply tube 24, a shift converter 25 and the cell body in that order. A fuel gas exhaust part is constituted of the flow of fuel gas connecting the cell body, the burner 26B of the reformer 26, a piping 28, the mixer 21 and the turbine 18B in that order. |
