<P>PROBLEM TO BE SOLVED: To provide a technique for suppressing a reaction gas flow into a gap formed around a conductive porous material in a fuel battery. <P>SOLUTION: The fuel battery includes a power generating substance, the conductive porous material which is overlaid on the exterior of the power generating substance, contains channels for circulating the reaction gas, and supplies the reaction gas to the power generating substance, a separator which is overlaid on the exterior of the conductive porous material and supplies the reaction gas thereto, a first seal portion which is formed along an end face of the power generating substance and forms a seal line between the first seal portion and the separator for suppressing a leak of the reaction gas from the inside to the outside of the fuel battery, and a second seal portion which is formed along the end face of the conductive porous material, suppresses a reaction gas flow from the conductive porous material into a space formed by the first seal portion, the separator, and the power generating substance, is so disposed as to be held at least between the separator and the power generating substance, and has a recession formed in contact with the power generating substance. <P>COPYRIGHT: (C)2009,JPO&INPIT |
