Abstract
A cell unit for use in a solid oxide fuel cell has a laminate structure including a cell element and a separator. The cell element includes a dense and planar solid electrolyte having a rectangular plane shape, and an air electrode film and a fuel electrode film provided on opposite surfaces of the flat solid electrolyte, respectively. The separator is made of a dense electron conductor. A plurality of oxidizing gas flow paths are defined between the separator and the air electrode, and the cell element has a rectangular planar shape and a ratio of a short side to a long side of the rectangular planar shape is not less than 2.
