<P>PROBLEM TO BE SOLVED: To provide a reactor that suppresses the occurrence of "the separation of a joint part" in a solid oxide fuel cell having a stack structure in a case where the number of stacks is increased. <P>SOLUTION: The fuel cell has the stack structure formed by alternately stacking and joining a plurality of thin plate bodies 11 between which chemical reaction occurs, and a plurality of separators 12 for separating two types of gas (air and fuel gas) required for chemical reaction with each other. Out of the plurality of separators 12, the highly rigid separator 12B (shown by dots) whose flat portion 12a has a greater thickness (t=tB) and higher rigidity is partially inserted thereinto and the rest is a normal separator 12A whose flat portion 12a has smaller thickness (t=tA(<tB)) and lower rigidity. This reliably suppresses the occurrence of "the separation of the joint part" resulting from "stress concentration due to an increase in the number of stacks" in the case that the number of stacks is increased. <P>COPYRIGHT: (C)2010,JPO&INPIT |
