A leak detection mechanism for use with a pressurized system that relates generally to an assembly for connecting a conduit to a component. The fiber composite sheet includes a first fiber layer, a core layer, and a second fiber layer. The first electrode, the organic material layer, and the second electrode form layered structure and at least one layer of the organic material layer include the compound of Formula 1 or the compound of Formula 1 into which a thermosetting or photo-crosslinkable functional group is introduced. Additionally, a NaOH supply for supplying NaOH to the condenser and an oxidizing catalyst supply for supplying an oxidizing catalyst to the condenser, are likewise used to produce cleaned flue gas for release to the atmosphere. The first and the second currents are added to generate a third current, which is mirrored to generate a fourth current proportional to the third current.
