PROBLEM TO BE SOLVED: To provide a raw material supply device for a fuel cell, capable of stabilizing power generated in the fuel cell by preventing a fuel gas to flow in a reverse direction to stabilize supply thereof.SOLUTION: A raw material mixer 50 equipped in a raw material supply device 10 for a fuel cell comprises a casing 51, a first raw material introducing pipe 61, a second raw material introducing pipe 62, a heating part 80 and a leading out pipe. The raw material mixer 50 mixes in a mixing passage 58 a first raw material with a second raw material vaporized by the heating part 80, to generate a mixed gas to be used for a power generation reaction of the fuel cell. Inner end sides of the first raw material introducing pipe 61 and the second raw material introducing pipe 62 have opening portions 64 and 68 respectively, the opening portions opening into the mixing passage 58. The mixed gas flows along the mixing passage 58 towards the leading out pipe side. The opening portion 68 of the second raw material introducing pipe 62 is arranged rearward in the flowing direction of the mixed gas with respect to the opening portion 64 of the first raw material introducing pipe 61. |
