PURPOSE:To obtain a lamellar catalyst having a uniform thickness distribution by extruding coaxially a slurry contg. a catalyst and a carrier or the like on a supporter such as a pipe and a rod, drying it to make a ring-shaped green body and opening it to make a lamellar shape. CONSTITUTION:In relation to a lamellar catalyst used for a reforming type fuel cell or the like, both a slurry 11 contg. a catalyst, a carrier and an aid catalyst, if necessary, and a supporter 12 such as a pipe and a rod are inserted into a vessel or an extruder provided with a mouthpiece having a prescribed shape and this supporter 12 is coaxially extruded from the mouthpiece having the prescribed shape together with the slurry 11 while sticking the slurry 11 on the supporter 12. A ring-shaped green body is obtained by heating the ring- shaped slurry on the supporter 12 and a lamellar green body is obtained by opening it in the extrusion direction on the supporter 12 and developing it. In such a way, the lamellar catalyst having a regular thickness distribution in accordance with the mouthpiece shape is obtained. |
