A fuel cell module includes a fuel cell unit and a casing. The casing has hollow surface members including a front surface member, a rear surface member, a right surface member, a left surface member, and a lower surface member. A single continuous air channel is formed by connecting spaces inside of these surface members. The air channel has a fluid inlet on the front surface member for allowing the air to flow initially in the front surface member. A first flange and a second flange are provided on the front surface member.

Fuel cell module

A fuel cell module includes a fuel cell stack, a reformer, and a hydrodesulfurizer. A fuel gas is supplied to the fuel cell stack through a fuel gas supply channel, and the reformer and the hydrodesulfurizer are provided for the fuel gas supply channel. A fuel exhaust gas is discharged from the fuel cell stack into a fuel exhaust gas channel, and a recycling channel is connected to the fuel exhaust gas channel, for circulating some of the fuel exhaust gas to return to a position of the fuel gas supply channel, the position provided upstream of the reformer and the hydrodesulfurizer.

In a fuel cell stack constituting a fuel cell module, electrolyte/electrode assemblies and separators are alternately laminated. An electrolyte/electrode assembly is arranged on one end of the fuel cell stack in the lamination direction, while a separator is arranged on the other end of the fuel cell stack in the lamination direction. A terminal separator is arranged adjacent to the electrolyte/electrode assembly, while a load relaxation member is arranged adjacent to the separator. The terminal separator controls the supply of a fuel gas to a fuel gas channel, and the load relaxation member is configured of a laminate of a plurality of flat metal plates.

In a fuel cell stack constituting a fuel cell module, electrolyte/electrode assemblies and separators are alternately laminated. An electrolyte/electrode assembly and a terminal separator are arranged on one end of the fuel cell stack in the lamination direction in this order outwardly, and a dummy electrolyte/electrode assembly and a terminal separator are arranged on the other end of the fuel cell stack in the lamination direction in this order outwardly. The dummy electrolyte/electrode assembly is so formed as to have the same shape as the electrolyte/electrode assemblies, while having conductivity but not having a power generation function.
