Provided is a desulfurizer that, with a simple configuration, can increase desulfurization efficiency by improving fuel dispersion properties. The desulfurizer (100), which is provided on the upstream side of a reformer in a fuel cell system and eliminates sulfur compounds in a gaseous fuel, is provided with: a rectangular-solid-shaped vessel (4) having a fuel inlet (5) and a fuel outlet (9); and a duct formation body disposed within the vessel (4). The duct formation body is provided with: a rectangular partition section (2); and a rectangular dispersion section (3). Three sides of the partition section (2) respectively are perpendicularly affixed to the upper surface (4a), front side surface (4c) and back side surface (4d) of the vessel (4), and the remaining side is perpendicularly affixed to the dispersion section (3). The dispersion section (3) has a pair of parallel sides that do not contact the inner walls of the vessel (4), and, at a position that is parallel to the bottom surface of the vessel (4) at a predetermined spacing, the other pair of sides respectively are perpendicularly affixed to the inner wall of the front side surface (4c) and the back side surface (4d) of the vessel (4), and the side of the partition section (2) that does not contact the vessel (4). The fuel inlet (5) and fuel outlet (9) are positioned towards the upper surface of the vessel (4) from the dispersion section (3), and are separated by the partition section (2). |
