<P>PROBLEM TO BE SOLVED: To provide a cell stack and a fuel cell capable of preventing deterioration with time of electrical connection between cells, and of keeping power generation performance over a long time. <P>SOLUTION: This cell stack 35 is so structured that a plurality of plate-like fuel cells 33 each having a gas circulation hole 34 in its inside, and an outside electrode 33d and an inter-connector 33e formed oppositely to each other are arranged; and the outside electrode 33d of each one-side fuel cell 33 is electrically connected to the inter-connecter 33e of the other-side fuel cell 33. The outside surfaces of the outside electrode 33d and/or the inter-connector 33e of the fuel cell 33 each have an irregular shape, and the irregular part(s) of the outside electrode 33d and/or the inter-connector 33d of the one-side fuel cell 33 is(are) directly connected to the inter-connector 33e and/or the outside electrode 33d of the other-side fuel cell 33. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
