Description

Unit module of fuel cell humidifier and fuel cell humidifier comprising same Technical Field The present disclosure relates to a unit module of a fuel cell humidifier and a fuel cell humidifier including the same, and more particularly, to a unit module of a fuel cell humidifier and a fuel cell humidifier including the same, in which a unit module including a plurality of cores is manufactured, and a fuel cell humidifier is manufactured using the unit module, so that the fuel cell humidifier can be manufactured in various forms. Background A fuel cell is a power generation cell that generates electricity by combining hydrogen and oxygen. Unlike typical chemical cells (such as primary cells or secondary cells), fuel cells can continuously generate electricity as long as hydrogen and oxygen are supplied, and they have an advantage of about twice the efficiency of an internal combustion engine because they have no heat loss. The fuel cell system includes a stack that is a power generation assembly of unit fuel cells each composed of a positive electrode and a negative electrode, an air supply device for supplying air to the positive electrode of the fuel cell, and a hydrogen supply device for supplying hydrogen to the negative electrode of the fuel cell. In order for the ion exchange membrane of the Membrane Electrode Assembly (MEA) of a polymer fuel cell of a fuel cell system to work smoothly, a proper amount of moisture is required, and for this purpose, a humidifier is provided in the air supply device of the fuel cell system to humidify the air supplied to the fuel cell. The humidifier humidifies the dry gas supplied through the air compressor of the air supply device using moisture in the high-temperature humid exhaust gas discharged from the anode of the fuel cell, and supplies the humidified air to the anode of the fuel cell. The fuel cell humidifier uses a membrane humidification method. The membrane humidifier performs membrane humidification by a gas-to-gas moisture exchange method between high-temperature humid exhaust gas discharged from the anode of the fuel cell and dry gas supplied through an air compressor. The fuel cell humidifier may be provided with a core in which a humidifying membrane formed of a hollow fiber membrane is arranged. The drying gas passes through the hollow fiber membranes through one side and the other side of the core, and openings (windows) open to the outside are provided on the side surfaces of the core. The exhaust gas flows into the core through the openings of the core, and the exhaust gas flowing into the core exchanges moisture with the dry gas passing through the hollow fiber membranes. However, in the related art, the fuel cell humidifier using the core has the following problems. The housing of the fuel cell humidifier may be provided with a plurality of cores, and the number of cores provided in the housing may vary according to the amount of humidified air supplied to the fuel cell. For the fuel cell humidifier using the core, there is a problem in that a separate housing must be manufactured according to the number of cores installed inside the housing. In addition, the fuel cell humidifiers in the art have a problem in that manufacturing costs are excessively high because they must be manufactured in various ways according to the amount of humidified air supplied to the fuel cell. Further, in the art, the fuel cell humidifier using the core has a problem that it is difficult to replace the core when the humidifying membrane inside the core is damaged. The humidification membrane inside the core may be damaged by the use of the fuel cell humidifier, in which case the core must be replaced. However, in the art, the fuel cell humidifier using the core has a problem in that it is difficult to replace the core damaged by the humidifying membrane because the core and the housing are formed as one body. Disclosure of Invention Technical problem The present disclosure is directed to solving the above-described problems, and more particularly, to a unit module of a fuel cell humidifier and a fuel cell humidifier including the same, in which a unit module including a plurality of cores is manufactured, and a fuel cell humidifier is manufactured using the unit module, so that the fuel cell humidifier can be manufactured in various forms. Technical proposal In order to solve the above-described problems, a unit module of a fuel cell humidifier according to the present disclosure includes a module case formed in a hexahedral shape and having first openings in an upper surface, a lower surface, a front surface, and a rear surface, and a core mounted on the module case and having a humidifying film therein, wherein the core is formed in a column shape and fixed to one side surface and the other side surface of the module case, and one or more cores are mounted in the module case. In order to solve the above-described problems, the unit module of the fuel cell humidifier ac
