PURPOSE:To provide a fuel cell of high reliability by preventing corrosion of various kinds of materials. CONSTITUTION:A gas seal member 12 and an O-ring 13 are interposed between a fuel cell lamination 14 and a manifold 11, between which an intermediate electrode 19 is disposed on a side of the O-ring 13 while an insulating film 21 is disposed on a side of the manifold 11 along the O-ring 13. The intermediate electrode 19 is located in approximately the same height as an undermost electrode of the fuel cell lamination 14, where at least one point is introduced out so as to be electrically connected. After passing an ammeter 22, the introducing-out portion of the intermediate electrode 19 is connected at one end thereof to the manifold 11 serving as an earth while at the other end thereof to a current collecting plate 17 via a variable resistor 23 and a DC power source 24. |
