<P>PROBLEM TO BE SOLVED: To provide a fuel battery cell stack unit improved in reliability. <P>SOLUTION: The fuel battery cell stack unit 62 is composed of a plurality of fuel battery cell stacks 30, 40, and a porous base body having holes inside includes a peripheral surface formed of a peripheral surface and a connecting surface. Each of the fuel battery cell stacks is electrically connected in series with each other, and the stack unit includes a plurality of first fuel battery cell stacks 30 and second fuel battery cell stacks 40 arranged at the other end side. On each first fuel battery cell stack, a first electric current path and a second electric current path making an electric current flow in an opposite direction with respect to each other are formed. Each of the first fuel battery cell stacks makes the electric current flow along a first connection surface from a fuel electrode terminal of a first peripheral surface side of the base body toward an air electrode terminal of a second peripheral surface side, and makes the electric current flow along a second connection surface from a fuel electrode terminal of a second peripheral surface side toward an air electrode terminal of a first peripheral surface side. <P>COPYRIGHT: (C)2011,JPO&INPIT |
