A heat exchanger (50) of a fuel cell module (12) includes a plurality of heat exchange pipes (64) connected to an oxygen-containing gas supply chamber (70a) at one end, and connected to an oxygen-containing gas discharge chamber (70b) at the other end. An end of an oxygen-containing gas inlet pipe (72) for guiding the oxygen-containing gas to the oxygen-containing gas supply chamber (70a) is provided in the oxygen-containing gas supply chamber (70a). A plurality of first inlet holes (73a) extend through the oxygen-containing gas inlet pipe (72) in an axial direction, and a plurality of second inlet holes (73b) extend through the oxygen-containing gas inlet pipe (72) radially. The total area of openings of the first inlet holes (73a) is smaller than the total area of openings of the second inlet holes (73b). |
