A pressing piece 38 of insulator is provided between the outer coil 12 and the inner coil 14, and the coils 12 and 14 are kept separate from each other. The pressing piece 38 is fixed to the extension 36 of a yoke 26 by the one side. The outer coil 12 is surrounded with a thin- plate cover 40. The thin-plate cover 40 is made to function as an outer mold when the outer coil is manufactured. An insulator layer 42 is provided to the outer and inner periphery of the outer coil 12 respectively. When the outer coil 12 is manufactured, an insulator layer 42 is wound on the outer periphery of the coil main body, and then the thin-plate sheathing 40 is wound thereon.

摘要： PURPOSE:To prevent oxygen from being generated by electrolysis of water and the component parts of a methanol fuel cell from being deteriorated so as to enhance the reliability of the methanol fuel cell and make the cell life longer by causing methanol contained in an anolyte and water to electrically and chemically react with each other within a manifold in order to yield carbon dioxide gas and hydrogen gas. CONSTITUTION:When anolyte 50 is fed into a methanol fuel cell from an anolyte entrance 52 a fuel chamber 51 is filled with the anolyte 50 through the manifold 42 of a carbon separator 40 as a main pipeline and through a branching line 43, and when air 60 of an oxidizing agent is fed into an oxidizing agent chamber 61 a potential difference between the fuel electrode 20 and oxidizing agent electrode 30 of each single cell occurs so that the single cells are connected in series. Under these conditions, liquid short-circuit occurs as in the electrical equivalent circuit of a cell stack 3 so that a current is caused to flow through the anolyte 50. In this case, current flows first from an auxiliary electrode 87 having catalyst and a reaction occurs in the auxiliary electrode 87 so that carbon dioxide gas and hydrogen gas are produced. Thus generation of oxygen causing electrolyte corrosion of the carbon separator 40 is restratined and the life of a laminated cell device is extended.

摘要： PURPOSE:To enable the efficient operation of a liquid fuel cell even if the concentration of fuel is heightened, by providing a fuel permeation suppressor of a prescribed fuel permeation rate in a fuel feed system including the fuel electrode of the cell. CONSTITUTION:In a liquid fuel cell 1, a fuel electrode 2 and an oxidizer electrode 3 face each other across an electrolyte chamber 4, and fuel 71 and an oxidizer 81 are fed to a fuel chamber 5 and an oxidizer chamber 6 respectively. To manufacture the fuel electrode 2, a base body 21 such as carbon paper is made water-repellent, a catalyst layer 22 is bonded thereto, grains of carbon black or the like are mixed with those of fluorinated graphite or the like and kneaded with a dispersion of fluorine resin grains, and the kneaded mixture is applied and then baked to become a fuel permeation suppressing layer 9 whose fuel permeation rate is 1X10 mol/cm .min.l or less. As a result, the quantity of fuel permeation in a fuel feed system is easily suppressed to enhance the efficiency of operation by feeding the fuel of high concentration.

摘要： PURPOSE:To form a concentration detector having high reliability, high sensitivity, and simple construction by bonding a fuel retarding layer which retards permeation of fuel to an anode through a catalyst layer. CONSTITUTION:A fuel retarding layer 17b is arranged in an anode 17 through a catalyst layer 21. The fuel retarding layer 17b is formed by making carbon fibers in a paper form and immersing it in polytetrafluoroethylene fine particle dispersion, then baking them to control permeability and water repellent property. By this treatment, the premeability of fuel is controlled to, for example, 7X10 mol/cm , min., mol/l. A platinum family catalyst layer 21 is bonded to the fuel retarding layer 17b by placing the mixture obtained by kneading the catalyst layer material and polytetrafluoroethylene fine particle dispersion on one side of the layer 17b and baking. They are bonded to an anode comprising, for example, tantalum. The electrode is fixed with a frame so that fuel enters the electrode from the fuel retarding layer.

摘要： PURPOSE:To achieve a stable and highly accurate measurement without electric contact with an electrolytic liquid from outside, by detecting a partial vapor pressure of a liquid fuel in the gaseous phase of the electrolytic liquid mixed with the liquid fuel with a semiconductor gas sensor. CONSTITUTION:A fuel pole chamber 11 and an air pole chamber 12 are arranged on both sides of a laminated fuel battery 10 and an electrolytic liquid 18 in an electrolytic liquid reservoir 17 is mixed with a liquid fuel 16 from a tank 15 to be supplied and circulated with a pump 14 to the fuel pole chamber 11 through an electrolytic liquid reservoir 17 and supply paths 11A and 11B. Air for an oxidizing agent is supplied to the air pole chamber 12 with a fan 13 through supply paths 12A and 12B. Moreover, a semiconductor gas sensor 26 is arranged in the gaseous phase of the liquid reservoir 17 and the partial vapor pressure of fuel in the gaseous phase, hence changes in the resistance of the gas sensor 26 due to the gas density thereof, is detected with an ammeter 21 to measure the density of the liquid fuel in the electrolytic liquid 18. Then, a temperature correction of a sensor 20 at a correcting section 20 is done with a temperature detection thermistor 25 while the supply of the liquid fuel 16 from the fuel tank 15 is controlled by adjusting the opening/closing frequency of a solenoid valve 19.
