PROBLEM TO BE SOLVED: To supply first reaction gas uniformly to a cell stack, in a solid oxide fuel cell device.SOLUTION: A solid oxide fuel cell device includes a cell stack where multiple solid oxide fuel battery cells, generating electricity by reaction of first reaction gas supplied to the outer surface and second reaction gas supplied to an internal flow path, are arranged, a container for containing the cell stack, a first reaction gas flow path attached to the inside or outside of the container, and supplying the first reaction gas to the outer surface of the fuel battery cells, and multiple first reaction gas spouts provided in the first reaction gas flow path, and ejecting the first reaction gas to the outer surface of the fuel battery cells. The multiple first reaction gas spouts have focusing spouts for ejecting the first reaction gas so as to be focused at predetermined places in the container, and diverging spouts for ejecting the first reaction gas so as to be diverged into the container.SELECTED DRAWING: Figure 4 【課題】固体酸化物形燃料電池装置において、セルスタックに第１反応ガスを均等に供給する【解決手段】外表面に供給される第１反応ガスと、内部流路に供給される第２反応ガスとの反応により発電する固体酸化物形燃料電池セルを複数配置したセルスタックと、セルスタックを内包する容器と、容器の内部又は外部に取り付けられ、燃料電池セルの外表面に第１反応ガスを供給するための第１反応ガス流路と、第１反応ガス流路に設けられ、燃料電池セルの外表面に第１反応ガスを噴出させる複数の第１反応ガス噴出孔と、を備え、複数の第１反応ガス噴出孔は第１反応ガスが容器内の所定箇所に集束するように噴出させる集束型噴出孔と、第１反応ガスが容器の内部に発散する発散型噴出孔とを有する。【選択図】図４
