PROBLEM TO BE SOLVED: To provide a fuel cell module that can surely supply a fuel cell stack with hydrogen-rich modified gas over a long period of time.SOLUTION: The fuel cell module M1 including a plurality of fuel cell stacks 1A, 1B of rectangular parallelepiped shape formed by alternately laminating power generating cells and separators, causes power generation reaction by supplying modified fuel gas to a fuel electrode layer, and oxidizer gas to an oxidizer electrode layer. A plurality of reformers 31-33 for reforming fuel gas are arranged around the fuel cell stacks. The prior stage side reformer is arranged at a part with a small heat receiving amount, and the subsequent stage reformer is arranged at a part with a large heat receiving amount. The reformers from the foremost stage to the last stage are connected in order by fuel piping, and a discharge port of the reformer in the last stage is connected to the fuel electrode layer of the fuel cell stack so that fuel gas passes through the subsequent stage side reformer after passing through the prior stage side reformer and is eventually supplied to the fuel electrode layer of the fuel cell stack. |
