Abstract: An object is to provide an electrode for electrolysis which is preferable in generation of ozone water usable in cleaning and sterilizing of water and sewage, or cleaning in a semiconductor device manufacturing process by an electrolysis process, and a method of manufacturing this electrode for electrolysis. The surface of a conductive substrate constituting the electrode for electrolysis is coated with a noble metal such as platinum or a noble metal oxide to form an intermediate layer, further a surface layer is constituted of a dielectric material on the surface of the intermediate layer, and the surface layer is provided with holes.

Abstract: A fuel cell that prevents the cross-over of liquid fuel within the fuel cell and the drop in cell voltage due to methanol oxidization on a cathode so as to enhance cell characteristics. A cell according to the present invention is provided with an anode and a cathode at both sides of an electrolyte layer, supplies liquid fuel to the anode, supplies oxidant to the cathode, and contains a fuel complexation material which forms a complex with a liquid fuel.

Abstract: There are provided an electrode for electrolysis which takes into consideration safety to human bodies and environmental pollution upon disposal of the electrode, produces ozone with high efficiency and has excellent durability, a production process of the electrode, and an active oxygen producing device using the electrode. In an electrode 5 for electrolysis which has an electrode catalyst at least on the surface and produces ozone or active oxygen in for-treatment water by electrolysis, the electrode catalyst contains a dielectric which constitutes more than 70% of the surface area of the electrode catalyst.

Abstract: An object is to provide an ozone production device capable of producing ozone in an electrolysis target liquid easily without performing any laborious assembly operation and with a high efficiency. In the ozone production device, a voltage is applied between an anode and a cathode, and ozone is produced in the electrolysis target liquid by electrolysis, the anode is integrated with the cathode via a predetermined interval without separating the anode from the cathode, and an electrolytic portion is constituted. Moreover, the anode and cathode comprise water-permeability members (mesh form) capable of passing the electrolysis target liquid.
