To provide a fuel cell module structure including a heat exchanger capable of preventing leakage of oxygen containing gas in a flow path and reducing the cost. The fuel cell module, which includes: a power-generating chamber that receives fuel cells; and a casing having a generally rectangular shape enclosing the power-generating chamber, wherein right and left side walls and an upper wall of the casing are hollow walls constituted of an outer shell member and an inner shell member disposed parallel to each other with a predetermined distance therebetween to form a reaction gas circulation space, each of the outer shell member and the inner shell member is formed in a U-like shape in cross section, a reaction gas introduction member vertically extending downward from the inner shell member of the upper wall into the power-generating chamber and being communicated with the reaction gas circulation space to introduce a reaction gas into the power-generating chamber.
