摘要:
An electricity leading method for a gas diffusion electrode is provided, by which a gas diffusion electrode is easily fixed to a cathode current collecting frame, the contact part has reduced electrical resistance, even an electrically insulating mesh sheet can be utilized as a gas chamber, and only the gas diffusion electrode can be replaced in renewal of the electrode. The method includes preparing a gas diffusion electrode by sandwiching a conductor made of a highly conductive metallic mesh or spongy processed material in catalyst layers or attaching a catalyst layer onto the conductor while leaving the conductor exposed in the outer periphery of the electrode, and electrically connecting the exposed part of the conductor to a cathode chamber current collecting frame.

[Problems] The liquid pressure of an anode chamber in a two-chamber ion exchange membrane electrolytic cell using a gas diffusion electrode are different among one another depending on depths so that the liquid pressures are applied on an anode or an ion exchange membrane, thereby introducing damage or deformation of the elements.[Means for Solving] A cushion material 10 is accommodated between a cathode gas chamber back plate 9 and a gas diffusion electrode 7 of an ion exchange membrane electrolytic cell 1 such that a repulsive force of the cushion material at the bottom part of the cathode gas chamber is larger than that at the top part. The excessive pressure applied to an ion exchange membrane is suppressed to prevent the generation of scratches or the like by decreasing the repulsive force of the cushion material toward the top in accordance with a differential pressure between an anode chamber pressure and a cathode gas chamber pressure.

There is provided a method of production of chlorine.sodium hydroxide capable of being operated stably and economically by preventing calcium from being deposited in an ion exchange membrane. The liquid retention layer 3 having a liquid retention amount per unit volume of the liquid retention layer of 0.10 g-H2O/cm3 or more and 0.80 g-H2O/cm3 or less is put between the ion exchange membrane 12 and the gas diffusion electrode 16. Calcium ions transferred through the ion exchange membrane 12 easily diffuse, thereby making it possible to suppress increase in an electrolytic voltage and drop in current efficiency generated by deposition of the calcium ions inside the ion exchange membrane 12.

摘要:
A receiving unit receives from a second terminal, a switching request message requesting switching of a counterpart of a communication that a third terminal is establishing with a first terminal, from the first terminal to the second terminal. When receiving the switching request message, a selecting unit selects one of the second and third terminals based on a predetermined rule, as a transmission source terminal that transmits an establishment request message requesting establishment of a communication between the second terminal and the third terminal. A transmitting unit transmits to the transmission source terminal, a transmission request message requesting transmission of the establishment request message.

In a gas diffusion electrode assembly, and in an electrolyzer using the same, a bonding piece having on at least one surface a perfluorosulfonic acid layer, a perfluorosulfonyl fluoride layer or an alkyl ester of perfluorocarboxylic acid layer is positioned at its perfluoro compound layer surface with respect to the gas diffusion electrode assembly. Adjacent gas diffusion electrodes are heat fusion bonded together, or heat fusion bonding is carried out using the bonding piece in a frame form. Adjacent gas diffusion electrodes are sealed up by heat fusion bonding, using a material that is similar to the material that forms the gas diffusion electrodes.
