An apparatus for controlling a cold start and a cold shutdown (CSD) of a fuel cell system and a method thereof are provided. A monitoring device may individually monitor at least one of an amount of accumulated power and/or an accumulated driving time of one or more fuel cell stacks. A controller may select a representative fuel cell stack among the one or more fuel cell stacks, based on the amount of accumulated power and/or the amount of accumulated driving time, performs a cold start of the representative fuel cell stack, and perform cold starts of the remaining fuel cell stacks, using power of the representative fuel cell stack after the cold start of the selected representative fuel cell stack is completed. The apparatus makes power used for a cold start and a CSD highly efficient.

Apparatus for controlling fuel cell system and method thereof

A camera module according to an embodiment of the present invention includes: a lens group; a lens support unit for accommodating the lens group; a magnet arranged on the outer surface of the lens support unit; a yoke portion spaced apart from the magnet and arranged to face the magnet; and a coil arranged on the yoke portion so as to be spaced apart from and to face the magnet between the magnet and the yoke portion, wherein the lens group, the lens support unit, and the magnet move together along an optical axis according to a current applied to the coil, the yoke portion includes a first yoke and a second yoke arranged on the first yoke, the second yoke is arranged between the first yoke and the coil, and magnetism of the first yoke is stronger than that of the second yoke.

Camera actuator and camera module comprising same

A method of distributing power in a fuel cell system including a plurality of fuel cell stacks, includes determining, by a controller, a total system power demand, which is a power demand of the fuel cell system, determining an operation order of the fuel cell stacks based on a state of the fuel cell stacks, determining the number of operation fuel cell stacks among the plurality of fuel cell stacks based on the total system power demand and an average available power of the fuel cell stacks, determining operation target fuel cell stacks based on the operation order of the fuel cell stacks and the number of operation fuel cell stacks, and determining a power demand of each of the operation target fuel cell stacks based on the total system power demand and an effective catalyst reaction area ratio of each fuel cell stack included in the operation target fuel cell stacks.

Method of distributing power in fuel cell system

A start control system of a fuel cell includes: a fuel cell configured to generate power upon receiving air and fuel; an air supply system configured to supply air to a cathode of the fuel cell through an air supply line; a fuel supply system configured to supply fuel to an anode of the fuel cell through a fuel supply line that re-circulates fuel discharged from an outlet of the anode of the fuel cell to an inlet of the anode to supply fuel; an air controller configured to control the air supply system such that air flowing into the air supply line bypasses the cathode of the fuel cell when a start ON signal is input; and a fuel controller configured to supply new fuel to the fuel supply line and to control the fuel supply system to purge fuel of the fuel supply line.

Start control system and method of fuel cell

The present invention relates to a method for providing a search result list by a search engine and a system thereof, and more particularly, to a method for generating a search result list by reflecting importance information in processing the search result list corresponding to a predetermined keyword input from a user terminal by a search engine and a system thereof. According to the present invention, there is an effect that is possible to provide method and system for providing a search result list, capable of providing a search result list on the basis of importance information in which accuracy and information on the registration date of a corresponding content are reflected.
