The present disclosure relates to an IrOelectrodeposited porous titanium composite layer of a polymer electrolyte membrane water electrolysis apparatus serving as both a diffusion layer and an oxygen electrode, the apparatus including: a porous titanium (Ti) layer; and an electrodeposited iridium oxide (IrO) layer on the porous Ti layer. The IrOlayer may be uniformly deposited on a porous Ti layer through an electrolysis process, and the electrodeposited IrOlayer may play multiple roles as not only a catalyst layer toward oxygen evolution reaction (OER) on the surface of the Ti layer, but also a corrosion-protection layer which prevents an inner Ti layer from corrosion.

A robot cleaner having a monitoring function and minimizing power consumption and/or securing communication efficiency and a method of controlling a robot cleaner are provided. The robot cleaner may include at least one sound obtaining device; at least one image obtaining device; and a controller configured to determine whether a sound obtained through the at least one sound obtaining device is abnormal, sense a direction in which an abnormal sound is generated, and obtain images in the direction in which the abnormal sound is generated. The robot cleaner may automatically recognize a surrounding situation, and when necessary, the robot cleaner may rotate and/or move in a corresponding direction and/or position to obtain images or transmit the obtained images to a remote terminal, thereby minimizing power consumption of the robot cleaner with limited power.
