<P>PROBLEM TO BE SOLVED: To provide a fuel cell system that enhances efficiency, by removing moisture in exhausted fuel gas and carbon dioxide, and is capable of size reduction of the system, and setting moisture concentration suitable for enhancing efficiency. <P>SOLUTION: In order to remove moisture and carbon dioxide at the same time, a gas controller 16 for example is installed in the fuel cell system. The gas controller 16 removes carbon dioxide from the exhausted fuel gas by the gas liquid contact of splay liquid sprayed from a spray header 25 and the exhausted fuel gas, and condenses and removes water vapor in the exhausted fuel gas, by cooling the exhausted fuel gas with a cooling pipe 26. An aqueous solution of calcium hydroxide or an aqueous solution of magnesium hydroxide is used as alkaline water. The gas controller 16 controls the moisture concentration in the exhausted fuel gas to be in the range of 25-40% and the carbon dioxide concentration to be in the range of 0-15%. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
