    摘要： The sealing of the top and/or bottom of the cylindrical positive electrode of an air-cell is improved and leakage of the electrolyte from the jellied zinc negative electrode disposed within the positive electrode which is constituted of a collector layer, catalyst layer, and a porous layer is prevented. By utilizing a positive electrode constituted of a metallic collector layer made of a metal mesh or such, a catalyst layer disposed around said collector, and a fluororesin porous layer as an air diffusion layer, an outer cup and an inner cup are pressed on the top of the positive electrode in order to prevent the leakage of the electrolyte. The possible leakage of electrolyte from the bottom of the positive electrode can be prevented by providing a resin sealing body with a ring shaped indentation fitted to the bottom of a positive electrode, and by inserting this resin sealing body into the positive electrode cannister, and by pressing the side wall of the positive electrode cannister against the side of the resin sealing body, in order to fit the bottom of the positive electrode to the indentation of the resin sealing body.

    摘要： The invention provides a method for manufacturing a solid polymer electrolyte electrolyte fuel cell which exhibits higher performances by sufficiently and uniformly contacting the solid polymer electrolyte with a catalyst to increase the reaction area inside the electrode. The method comprises the steps of dispersing a carbon powder supporting a noble metal catalyst in an organic solvent to obtain a dispersion, mixing the resulting dispersion with an alcoholic solution of a solid polymer electrolyte to produce a colloid of the solid polymer electrolyte and simultaneously to obtain a mixed solution in which said colloid is adsorbed to the carbon powder, applying the mixed solution on one side of a gas-diffusion layer to produce an electrode, and pressing the resulting electrode on at least one side of a solid polymer electrolyte membrane to integrate them. Furthermore, a fluorocarbon polymer can be added, to thereby form a gas channel without excessive covering of the catalyst and increase gas permeability of the electrode. Thus, a solid polymer electrolyte fuel cell which exhibits high performances in a high current density area can be further provided.

    摘要： In a differential-type protective relay actuated to generate a signal necessary for the protection of a bus of an electric power system when a troubled current has flown through the bus, a gapped first transformer is used to receive an output from a current transformer which is adapted to detect each current in the bus. Each output of a first detection element, which is actuated when the output of the first transformer is higher than a preset level, is fed out to the exterior only when a value obtained by subtracting the sum of the maximum of the output of the first transformer and the value of a signal obtained by shifting the phase of the output through a predetermined angle from the value of a signal obtained by subjecting the output of the first transformer to full-wave transformation is equal to or lower than a preset value.
