摘要

PURPOSE:To improve the safety of cell operation with reduced temperature difference within the cell surface during steady state operation by constituting so that the direction of progress of original fuel gas quality improvement reaction on the surface of quality improvement and the direction of oxidizing gas flow on the cell reaction surface are opposite to each other. CONSTITUTION:A distribution section 20 of original fuel gas is inserted at the time of assembly between unit cells 1a and 1b. With this structure, the original fuel gas 6 supplied from the side parallel to the oxidizing agent gas 9 flow direction is distributed with the distributing section 20 and flows through a quality improving catalyst 5 in the direction opposite the oxidizing agent gas 9 flow and the quality is improved by quality improving reaction to be quality improved fuel gas 7. The quality improved gas 7 is supplied to the unit cells 1a and 1b in the direction perpendicular to both directions of the oxidizing agent gas 9 flow and the progress of the quality improving reaction. This causes to utilize both heat absorbing effects of quality improvement and the oxidizing agent gas, and the cooling of the cells is effected in both directions. As a result, temperature distribution within the cell surface is made uniform and the safety of operation is improved.
