A fuel cell system comprises first and second parallel fuel cell stacks (12, 14) in which a positive electrode and a negative electrode of adjoining terminal electrodes are set to be opposite to one another. First and second conductive plates (82, 180) are incorporated at ends on an identical side of the first and second fuel cell stacks (12, 14). First and second connecting plate sections (106, 182) extend from the first and second conductive plates ( 82, 180) closely to one another under the first and second fuel cell stacks (12, 14). The first and second connecting plate sections (106, 182) are electrically connected by flexible strand wires ( 186a, 186b). Accordingly, the fuel cell system reliably avoids stress caused by vibration or the like at a connecting portion for electrically connecting the first and second fuel cell stacks (12, 14) to one another.

What is claimed is: 1. A vehicle-carried fuel cell system provided with fuel cell stacks each comprising a plurality of fuel cell units, said fuel cell units each including a solid polymer ion exchange membrane interposed between an anode electrode and a cathode electrode, said plurality of fuel cell units being stacked in a horizontal direction with separators intervening therebetween, said fuel cell system comprising: first and second fuel cell stacks which are arranged in parallel to one another in a stacking direction, said first and second fuel cell stacks each being sandwiched by separate pairs of end plates so as to construct separate stacks, wherein a positive electrode is disposed on a side of said first fuel cell stack and a negative electrode is disposed on a side of second fuel cell stack; first and second electric power-deriving terminals, one of which is said positive electrode, the other of which is said negative electrode, and which are disposed on vertical surfaces at first ends in a stacking direction of said first and second fuel cell stacks; first and second conductive plates provided with first and second connecting sections which are incorporated at the inside of vertical surfaces at second opposing ends of said first and second fuel cell stacks; and a flexible connector for electrically connecting said first and second connecting sections, wherein the flexible connector reduces stress on the first and second conductive plates by allowing the first fuel stack to move relative to the second fuel cell stack. 2. The fuel cell system according to claim 1, wherein said first and second fuel cell stacks have a rectangular parallelepiped-shaped configuration, and each of said fuel cell stack is arranged such that a short side direction is oriented in a direction of gravity, and a long side direction is oriented in said horizontal direction. 3. The fuel cell system according to claim 1, wherein said flexible connector is provided with a strand wire obtained by twisting a plurality of conductive wires into a net-shaped configuration. 4. The fuel cell system according to claim 3, further comprising a rubber cover for covering said strand wire. 5. The fuel cell system according to claim 1, wherein said flexible connector is a cable. 6. The fuel cell system according to claim 1, wherein said first and second connecting sections are substantially fan-shaped plate members provided at corners of said first and second cell stacks. 7. The fuel cell system according to claim 1, wherein said first and second connecting sections are rod-shaped members. 8.
