Abstract: It is an object of the present invention to provide a dye-sensitized solar cell with high cell performance.

Abstract: The present invention provides a denitration catalyst which is designed to show a drop of the mechanical strength of the carrier to an acceptable extent even when used with an exhaust gas containing sulfur oxides while making the use of excellent water resistance or electrical insulating properties inherent to glass fibers and a process therefor. The denitration catalyst comprises a catalytically active component supported on a structure comprising a glass fiber free of B.sub.2 O.sub.3, an inorganic filler and an inorganic binder.

Abstract: An electric double layer capacitor having a rectangular cross-section for an excellent volumetric efficiency and a low internal resistance is disclosed. The capacitor comprises a plurality of sheet-like current collectors in one polarity and in the other polarity; the surfaces of the both collectors are formed into polarizable electrodes composed mainly of activated carbon with a binder; a plurality of separators interposed between the current collectors of the one polarity and those of the other polarity.

Abstract: An electric double layer capacitor of reduced internal resistance is manufactured using unit electrodes each consisting of a collector layer and a polarizable electrode layer bonded together through a diffusion layer composed of components of the two layers. To manufacture the capacitor, a pair of unit electrodes are disposed with the respective polarizable electrode layers facing each other and, after impregnation with an electrolyte, the peripheral surfaces of the unit electrodes are sealed with a sealant resin.

Abstract: An electric double layer capacitor which has a pair of polarizable electrodes, composed of electrically-conductive substrates. The substrates are coated in layers of a mixture of activated carbon with a water-soluble material-based binding agent, optionally including an agent for improving electric conductivity. The electrodes face each other interposed by a separator, and are impregnated with an electrolyte. The capacitor has the advantageous features of both conventional capacitors using an aqueous electrolyte and those capacitors using an organic solvent electrolyte; in other words, the capacitor can withstand high voltages while holding a low internal resistance.
