Abstract

PURPOSE:To unify temperature distribution in a cell, obtain uniform power generation energy and enable the improvement of cell performance by providing divisions in a manifold and a separator plate for forming respective gas passages with the sectional areas thereof gradually increased from an outlet side to an inlet side and making opposite the directions of fuel and oxidant gases flowing in fuel and oxidant gas passages on the adjacent same plane. CONSTITUTION:A plurality of manifold divisions 20 are provided in manifolds 7A and 9A for supplying and exhausting reaction gases and furthermore a separator plate 4a is provided with a separator division 21, thereby forming a plurality of fuel gas passages 5 and oxidant gas passages 6. And the cross sectional areas of said gas passages 5 and 6 are so made as to be gradually reduced from a fuel gas inlet part 22 to a fuel gas outlet part 23. And when the direction of gases flowing from the fuel gas inlet part 22 to the fuel gas outlet part 23 on a gas flow plane is normal at the first row as shown with an arrow mark, said direction is reverse at the second row. And the direction is made normal at the third row. As aforementioned, the gas flow directions at even and odd number rows are made opposite to each other.
