Abstract: There is provided an aqueous solution electrolysis method that makes it possible to reduce the amount of bubbles covering an electrode and generate gases such as hydrogen and oxygen with excellent energy efficiency. The method is an electrolysis method for electrolyzing an aqueous-solution-based electrolyte to generate at least any one of hydrogen, oxygen, and chlorine, wherein the electrolyte contains a water-soluble alcohol. For example, as the electrolyte, an alkali aqueous solution containing about 0.1 to about 10% by volume of a water-soluble alcohol including a tertiary alcohol, such as 2-methylpropan-2-ol and 2-methylbutan-2-ol, and about 1 to 10 mol/L of an alkali component may be subjected to water electrolysis, and the electrolyte is electrolyzed using, for example, an electrolytic cell having an anode chamber and a cathode chamber.

Abstract: An unmanned traveling vehicle includes a block information acquirer that acquires position information on blocks each of which is a range of positions in an area within which the unmanned traveling vehicle is allowed to travel and channel information indicating a wireless channel available inside each of the blocks, a position acquirer that acquires a current position of the unmanned traveling vehicle, a determiner that identifies a block including the current position acquired by the position acquirer from among the blocks with reference to the position information, and determines, with reference to the channel information, a wireless channel to be used for wireless communication inside the block identified, and a communicator that performs the wireless communication by the wireless channel determined by the determiner and indicated by the channel information.
