    Abstract: This application relates to an information output apparatus including at least one information output unit. The information output unit includes a coil unit connected to a power source to allow an electric current to flow therethrough and a base unit formed to accommodate the coil unit. The information output unit also includes an expression unit formed and arranged to allow a user to sense the expression unit and a driving unit arranged in the base unit to be separated from the coil unit. The driving unit is adjacent to the coil unit to be driven by the electric current flowing through the coil unit to perform an angular or rotational movement so as to move the expression unit in a first direction towards the coil unit and an opposite direction.

    Abstract: The present invention relates to a transition metal nitride support, a method of manufacturing the same, a metal catalyst and a platinum-alloy catalyst including the transition metal nitride support, and manufacturing methods thereof. The manufactured transition metal support prevents corrosion of the support and aggregation of the platinum catalyst, thereby exhibiting high oxygen reduction catalytic activity. Also, strong metal-support interaction (SMSI) can be stabilized, thus improving the durability of the catalyst. The transition metal support includes large pores uniformly distributed therein, thereby increasing the amount of the catalyst supported and minimizing mass-transfer resistance in a membrane- electrode assembly, increasing the performance of a polymer electrolyte membrane fuel cell. The metal catalyst includes platinum particles loaded on the transition metal nitride support, thus exhibiting superior durability and activity. The manufactured platinum-alloy catalyst decreases the use of expensive platinum, thus generating economic benefits and improving the inherent oxygen reduction performance.
