摘要： PURPOSE:To provide an optical fuel cell which uses light as a fuel source by furnishing a No.1 electrode consisting of porous catalyst in the middle between No.1 electrolyte with gas permeability and No.2 electrolyte including photocatalyst, and furnishing a No.2 electrode consisting of non-porous catalyst in a position adjacent to the No.1 electrolyte. CONSTITUTION:A load is inserted in connection between cell terminals 2, 3, and No.1 electrolyte 6 with gas permeability is formed being pinched by No.1 electrode 4 consisting of porous catalyst and No.2 electrode 5 consisting of non-porous catalyst. No.2 electrolyte 7 is formed as pinching the No.1 electrode 4 together with true No.1 electrolyte 6, and a photocatalyst 8 is dispersed in this No.2 electrolyte 7. Therein, one side of the No.1 electrode 4 is covered with a porous water-repelling film 4a, and the photocatalyst 8 is formed from particulates consisting of a semiconductor part and a metal part. When light energy is cast onto these photocatalyst particulates 8, oxygen is produced in the neighborhood of the surface of semiconductor while hydrogen is produced in the neighborhood of the surface of metal part. This allows achieving a cell which does not require supplying the fuel substantially.

摘要： PURPOSE:To dispense with a voltage regulating circuit and simplify a battery structure by converting the light energy into the electrochemical energy, electrically connecting a negative electrode or a positive electrode to a photo-electrode directly, and arranging the positive electrode or the negative electrode near the photo-electrode. CONSTITUTION:A photo-electrode 1 and a negative electrode 3 are electrically connected with a connecting lead wire 8, and an electrolyte 4 is brought into contact with the photo-electrode 1, positive electrode 2 and negative electrode 3. The energy band of the photo-electrode 1 is bent upward toward the electrolyte 4 side on the contact interface with the electrolyte 4. When the light energy is radiated to the surface of the photo-electrode 1, electrons are excited by a conduction band, and holes are generated on a valence band. The holes are conveyed to the electrolyte 4 side along the curve of the band, and the electrochemical oxidation reaction is generated on the surface of the light electrode 1. No voltage regulating circuit and the like is required, the conversion efficiency is improved, the battery structure is simplified and made small-sized.

摘要： PURPOSE:To lengthen the life of a battery with thin shape kept by forming an adhesive layer on a film base and embedding a part or the whole of a lead family base to decrease the contact area of the edge of the lead family base with a sulfuric acid electrolyte. CONSTITUTION:An adhesive layer 6 is formed on a plastic film base 4', and a part or the whole of lead family base 8 is embedded in the layer 6. An active material layer 7 is placed on the base 8, and an electrolyte is filled between a positive plate 1 and a negative plate 2. A film 4 also functions as a battery case, and the peripheries of the films 4, 4' are heat-sealed except for a safety vent 5 to form sealed structure. The thickness of the adhesive layer 6 is adjusted so that the lead family base 8 is suitably embedded in the layer 6. If the thickness of the lead family base is in the range of 50-100mum, that of the adhesive layer 6 is preferable to be adjusted to 30-150mum. Capacity drop of a battery attendant on charge-discharge cycles is decreased and the life is lengthened. The thickness of the battery is kept 1mm or less.

摘要： PURPOSE:To enhance the durability of a secondary battery and besides to make its thickness thinner by laying its positive electrode member, electrolyte and negative electrode member transversely on the same plane on the base plate of the battery case. CONSTITUTION:A positive electrode member 12 and a negative electrode member 13, each comb-shaped, are set in parallel on the one side surface (plane) of a flat-plate-like base plate 11a, and electrolyte 15 concerned with battery reaction is filled in the space between the electrode members 12 and 13. The positive electrode member 12 and the negative electrode member 13 are arranged so that their side faces may face each other. The progressing direction of the battery reaction at the time of charge and discharge is perpendicular to the thickness direction of the electrode members 12, 13, i.e., parallel to the tooth width direction of the electrodes. The electrode members 12, 13 can thereby be made thinner without any bad effect on the battery life.

摘要： PURPOSE:To keep effective reaction area of catalyst pellets as wide as possible by removing water which condenses in a catalyst container and retards a recombining reaction of an acid and hydrogen gas in a catalytic gas recombining equipment which installs in a storage battery such as a lead acid battery or an alkaline storage battery and recombines the acid and the hydrogen gas to form water in order to return into an electrolyte the acid and the hydrogen gas generating during use of the storage battery. CONSTITUTION:Water formed by combining of the acid and hydrogen gas in a catalyst container 3 penetrates by capillaly action into fine pores of catalyst pellets 2 applying no water-repellent treatment which is filled in the catalyst container 3. Thus, water which retards a recombining reaction of the acid and the hydrogen gas is removed. The condensed water is removed by catalyst pellets 2 applying no water-repellent treatment, therefore, water is effectively formed in the space between the catalyst container 3 and a container 4 by catalytic action of catalyst pellets 1 applying water-repellent treatment which is placed with the catalyst pellets 2 applying no water-repellent treatment in the catalyst container 3.

摘要： PURPOSE:To prevent liquid junction of electrolyte in a simple method, and achieve high voltage of a thin sealed lead-acid battery by providing a partition wall comprising a member to which the electrolyte is not permeable between a positive electrode member and a negative electrode member disposed on the same collector. CONSTITUTION:Formation liquid 31', 32', 33' is separated by partition walls 62, 63 without being mixed with each other. Move of ions thus occurs through the formation liquid 31', 32', 33' between electrodes 11', 12', 13' to be positive electrodes and electrodes 21', 22', 23' to be negative electrodes. The electrodes 11', 12', 13' to be the positive electrodes electrochemically thus become lead dioxide PbO2, that is the positive electrodes 11, 12, 13, and the electrodes 21', 22', 23' are activated to be lead Pb, that is the negative electrodes 21, 22, 23. A low-cost and high-voltage thin type sealed lead-acid battery can thus be produced.

摘要： PURPOSE:To provide a two electrode system sealed light oxygen secondary battery capable of charging. CONSTITUTION:A positive electrode 21 made of an oxygen catalyst, a negative electrode 22 made of a metallic negative electrode member 22a, an electrolyte 23 in contact with the positive electrode 21 and the negative electrode 22, and a battery case 27 into which the positive electrode 21, the negative electrode 22, and the electrolyte 23 are accommodated are arranged. A light receptor 27a from which rays enters the negative electrode member 22a is installed in the battery case 27. The electrolyte 23 is absorbed and held in a porous body 24. A battery is discharged with the oxidation reaction of the negative electrode member 22a and the reduction reaction of oxygen. By exposing the discharge product on the negative electrode member 22a to light energy, the discharge product is reduced, and at the same time oxygen is produced for charging. A charger is unnecessary because charge is conducted by light. Battery structure is simplified in two electrode system of the positive electrode and the negative electrode.
