A porous electrolytic solution reservoir which is capable of being impregnated with an electrolytic solution is provided in an exterior case so as to make contact with a separator. The average diameter of the pores in the electrolytic solution reservoir is greater than the average diameter of pores in the separator. The electrolytic solution reservoir is impregnated with a predetermined amount of electrolytic solution, so that the occupation ratio of electrolytic solution within the pores in the separator becomes 50% or more when fully charged, and the occupation ratio of electrolytic solution within the pores in the electrolytic solution reservoir becomes 100% or less when fully discharged.

Electric double layer capacitor

Provided is an electric double layer capacitor including a large capacity single cell having a large electrostatic capacity and a small capacity single cell are connected to the same exterior case in parallel, and a thickness of a separator of the large capacity single cell is made thicker than a thickness of a separator of the small capacity single cell. With this structure, a supply amount of an electrolyte solution to the large capacity single cell is markedly increased compared with the small capacity single cell, thereby being capable of preventing degradation of the large capacity single cells and the small capacity single cells and providing the electric double layer capacitor having an excellent cycle life and having a large power storage amount while keeping characteristics capable of instantaneously allowing large current to flow.

A compressor system includes a compressor, a turbine for driving the compressor, and an auxiliary burner. Compressed air from an external source is supplied to drive the turbine during start-up. The air compressed by the compressor is then supplied to the auxiliary burner to drive the turbine and the compressed air from the external source is shut-off to keep the compressor system running only by the compressed air from the compressor itself.
