Description

Fuel cell storage device and ship including the same The present invention relates to a fuel cell storage device and a ship including the same. Energy sources used in ships include fuel oils such as LFO (Light Fuel Oil) and natural gas. Furthermore, hydrogen energy is recently gaining attention as an alternative energy source capable of addressing the problem of fossil fuel depletion, and active research and development are being conducted on fuel cells, which serve as the medium for utilizing hydrogen energy. A fuel cell is a power generation system that generates electrical energy through the electrochemical reaction between hydrogen contained in hydrocarbon-based substances such as methanol, ethanol, and natural gas, and oxygen in the air. Specifically, as hydrogen and oxygen undergo an electrochemical reaction inside the fuel cell stack, the chemical energy of the fuel can be converted into electrical energy. Since the energy conversion efficiency is significantly higher than that of a conventional heat engine, fuel consumption and the emission of pollutants and greenhouse gases can be greatly reduced. For ships utilizing fuel cells as a power source, stacks must be replaced at regular intervals; consequently, maintenance space for stack replacement is essential when deploying stacks on a vessel. As such, since fuel cell installation requires a significant amount of space, there is a need for measures to efficiently deploy fuel cells and increase the installed capacity per unit area in environments with spatial constraints, such as ships.

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted. In addition, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the embodiments of the present invention. These terms are intended merely to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by these terms. Where it is stated that a component is "connected," "combined," or "joined" to another component, it should be understood that the component may be directly connected or joined to the other component, but that another component may also be "connected," "combined," or "joined" between each component. In this specification, the front-back, left-right, and up-down directions are referred to for convenience of explanation and may be directions orthogonal to one another. However, these directions are determined relatively, and the term "up-down direction" does not necessarily mean a vertical direction.
