The present invention relates to a hybrid dehumidification cooling and humidification heating system applied with MOF for a hydrogen fuel cell railway vehicle. It relates to a hybrid dehumidification cooling and humidification heating system applying MOF for a hydrogen fuel cell railway vehicle that enables heating.

Among various transportation means, railway is a representative means of transportation on land, and has the same fundamental elements as other transportation means, but has a big difference in that it is a special vehicle that must not depart from the rail and its power source is different.

These railways include electric railways with a relatively large transport scale, which operate trains or vehicles using electricity as power, light railways, which are medium and low-speed public transport modes with a relatively small transport scale compared to electric railways, and driving power by spark ignition of diesel engines. urban commuter vehicles that generate

However, the railway vehicles as described above have a problem in that they require various facilities for vehicle operation or cause environmental pollution by using electric power or fossil fuel as a power source.

In other words, an electric railway vehicle that uses electricity as its power source requires an electricity supply system and various structural facilities such as a substation facility and a power collecting facility for supplying the special high voltage transmitted from the power plant to the vehicle in order to supply a huge amount of power. In addition, maintenance vehicles using fossil fuels have a problem in that environmental pollution occurs due to the exhaustion of fossil fuels, which are finite resources, and the emission of CO ₂ gas due to the use of the fossil fuels.

Accordingly, an EV (Electric Vehicle) that uses a battery-operated motor as a power source, an HEV (Hybrid Electric Vehicle) that uses a mixture of an engine and a motor, and a PHEV (Plug- in Electric Vehicle), etc. Recently, instead of using a rechargeable battery, research on a fuel cell electric vehicle (FCEV) that uses a hydrogen fuel cell driven by hydrogen as a fuel is being actively conducted.

When water is electrolyzed, hydrogen and oxygen are generated at the electrode. A hydrogen fuel cell is a cell that uses the reverse reaction of electrolysis to supply hydrogen and oxygen to produce electricity. These hydrogen fuel cells do not cause any environmental pollution problems because only water vapor is generated as a by-product after electricity production. There is a big advantage. In a situation in which environmental pollution and resource depletion problems are becoming increasingly serious in recent years, the demand for practical use of such hydrogen fuel cell railway vehicles is increasing.

In addition, there is a problem that a lot of waste heat is generated during operation of the railway vehicle, and a heating and cooling system is essential due to its characteristics, but there is a problem that a lot of energy is required to implement this.
