Cell stack device, fuel cell module, fuel cell device, and method of fabricating cell stack device

Abstract

[Object] To provide a cell stack device, the power generation efficiency of which is improved, and a fuel cell module and a fuel cell device that include the cell stack device. [Solution] A cell stack device 1 includes a cell stack 2 that includes a plurality of fuel cells 3 electrically connected to one another and arranged, the fuel cells 3 that each includes a gas channel through which a reactant gas flows. In the cell stack device 1, the fuel cells 3 of the cell stack 2 are provided in the form of fuel cell groups that each include an arbitrary number of the fuel cells 3. In the cell stack device 1, the fuel cell groups are arranged such that average pressure loss values of the fuel cells 3 of the fuel cell groups increase sequentially from a central portion to an end portion side in a fuel cell 3 arrangement direction. Thus, the power generation efficiency of the cell stack device 1 can be improved.
