Description

Fuel cell storage case capable of constant temperature and humidity and operating method thereof The present invention relates to a fuel cell storage case capable of maintaining a constant temperature and humidity and a method for operating the same. More specifically, the invention relates to a fuel cell storage case capable of maintaining a constant temperature and humidity and a method for operating the same, which can prevent a decrease in the output performance of a fuel cell by having a constant temperature and humidity effect with a simple structure. In the case of fuel cells, particularly open-cathode polymer electrolyte membrane fuel cells (Open Cathode PEM Fuel Cells), there is a problem where the Membrane Electrode Assembly (MEA) dries out and output performance deteriorates when exposed to normal indoor or outdoor environments for a long period. To solve these problems, a method is used in which a separate chamber capable of maintaining constant temperature and humidity is constructed to store fuel cells in said chamber or to periodically forcibly operate the fuel cells. However, building a separate chamber is expensive, making it difficult for an individual to build, and forcibly operating the fuel cell is very inconvenient and cumbersome because it must be operated in situations where there is no need to operate the fuel cell, resulting in very low user convenience. Therefore, a technical concept is required for a storage case that can be constructed compactly and maintain constant temperature and humidity very simply, thereby preventing degradation of fuel cell output performance even during long-term storage.
