PURPOSE:To make a system simple and compact by installing an enlargement passage which forms part of fuel gas supply passage through a heat exchange partition in the back of manifolds in which air is introduced into a raction air channel and a cooling air channel. CONSTITUTION:An enlargement passage 16' which forms part of a supply passage of fuel gas reformed in a reformer 14 through a heat exchange partition 15 is formed in the back of manifolds 8, 8' in which air is commonly introduced into a reaction air channel 4 and a cooling air channel 6. The main component of the reformed gas is hydrogen having good heat conductivity and the flow rate of air also serving as cooling gas is sufficiently large. Since these gases are in contact with each other through the partition 15 in a wide area, heat exchange is efficiently conducted without use of separate heat exchangers, and high temperature reformed gas is cooled to optimum temperature to introduce into a cell 1. A system can be made simple and compact. |
