A UV-assisted advanced-ozonation water treatment system comprises a water treating tank, an ozonic water tank, an ozonized gas generator, and a UV light sourcedisposed in the water treating tankand having a UV-radiating surface, and an ozonic water jetting device including jetting nozzlesfor jetting the ozonic water onto the UV-radiating surface of the UV light source. An ozonized gas diffusing deviceis placed in the ozonic water tank. An ozonized gas generated by the ozonized gas generatorand compressed by a compressorat a pressure in the range of about 2 to about 3 kg/cmis diffused into the ozonic water tankby the ozonized gas diffusing device. A high-pressure, a high-ozone-concentration ozonic water produced in the ozonized water tankis jetted through the jetting nozzlesonto the UV-radiating surface

Positive electrode active material for nonaqueous electrolytic solution secondary batteries is made of a metal oxide. A content of coarse particles, of which particles sizes are 600% or more with respect to an average particle size of the metal oxide, is 1% or less by volume, and a content of high density particles, of which densities are 150% or more with respect to an average density of the metal oxide, is 1000 ppm or less. By using the positive electrode active material, battery characteristics and a manufacturing yield may be improved.

Each of gas manifolds which are disposed on the side surfaces of a cell stack is constituted by integrating a plate-like heat insulating member disposed on the outer surface of the cell stack and a heat and phosphoric acid resisting sheet member joined to cover the inner and side surfaces of the heat insulating member

Fuel cell having gas manifold

Gas manifolds which are excellent in both phosphoric acid proof and electric insulation and which have sufficient corrosion proof over a long period are provided. A resin sheet with high phosphoric acid proof is folded to have a size smaller than that of the corner sections of the inner plane of gas manifolds by the size corresponding to a thermal expansion, and the folded planes are thermally compressed in air tight to form box-shaped linings. These linings are applied to the inner planes of the gas manifolds. Patches are thermally compressed to the outer surface of the bottom section of the linings and each patch is fitted loosely with a male hook or a female hook. A female hook or a male hook for engaging with the hook on each patch is fitted on the inner plane of the gas manifolds at an opposing position. The linings can be fixed to the gas manifolds engageably and disengageably by these hooks.
