Description

Portable hydrogen production module and hydrogen fuel cell power generation system including the same The present invention relates to a portable hydrogen production module and a hydrogen fuel cell power generation system including the same. More specifically, it relates to a portable hydrogen production module and a hydrogen fuel cell power generation system including the same, which can produce hydrogen and generate electricity using the generated hydrogen without being affected by location, time, or weather, by appropriately mixing chemical hydrides and organic acid hydrate additives to obtain only a desired amount of hydrogen via a low-temperature pyrolysis method at a temperature convenient for personal portability. Fuel cell systems are systems that produce electrical energy through the chemical reaction of fuel, and research and development are continuously being conducted as an alternative to solve environmental problems. Existing hydrogen production systems include steam reforming and water electrolysis. First, steam reforming technology generates hydrogen through the thermal decomposition reaction of hydrocarbon fuels. While it has the advantage of enabling the mass production of high-purity hydrogen, it requires high temperature and pressure, inevitably leads to the large-scale release of carbon dioxide, a greenhouse gas. Furthermore, carbon monoxide produced as an impurity causes a rapid degradation in the performance of fuel cells (PEMFC). The water electrolysis method is a process that obtains hydrogen and oxygen through the electrolysis of water. Although water, the raw material, is relatively abundant, the process requires a large amount of electrical energy for electrolysis; in fact, the electrical energy required for the electrolysis itself is greater than the electricity generated from the hydrogen produced. Conventional portable hydrogen generators obtain hydrogen using a portable hydrogen tank called a 'hydrostick,' but this method has disadvantages such as requiring a separate system to refill the tank, being bulky and heavy for personal wear, and having high maintenance costs.
