PURPOSE: A flat plate type solid oxide fuel cell is provided to improve reaction rate of a fuel cell by increasing reaction area of a negative electrode functional layer, and to be able to apply to large area and high powder flat plate type solid oxide fuel cell. CONSTITUTION: A flat plate type solid oxide fuel cell(10a) comprises a negative electrode support(101a), a negative electrode functional layer(102a) in an upper part of the negative electrode support, and an electrolyte(103a) in the upper part of the negative electrode functional layer. The negative electrode functional layer has an uneven part in the opposite side of the side contacting with the negative electrode support, and has the thickness of 10-40 micron. The negative electrode support comprises one or more kinds selected from a group consisting of stainless steel, iron based alloy, and nickel based alloy. |
