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 deviceincludes a cell stackthat includes a plurality of fuel cellselectrically connected to one another and arranged, the fuel cellsthat each includes a gas channel through which a reactant gas flows. In the cell stack device, the fuel cellsof the cell stackare provided in the form of fuel cell groups that each include an arbitrary number of the fuel cells. In the cell stack device, the fuel cell groups are arranged such that average pressure loss values of the fuel cellsof the fuel cell groups increase sequentially from a central portion to an end portion side in a fuel cellarrangement direction. Thus, the power generation efficiency of the cell stack devicecan be improved.
