The present application relates to a gas detection element.
Hydrogen gas is used in various applications, including energy generation means such as batteries, energy storage means, and energy transfer means.
Hydrogen gas is a colorless, odorless, and flammable gas having a wide flammability limit in the air. Therefore, it is required to properly detect hydrogen gas leakage for safety purposes in any environment and/or apparatus in which hydrogen gas is handled.
FIG. 1 is a cross-sectional view schematically illustrating a configuration example of a gas detection element according to an embodiment of the present invention;
FIG. 2 is a cross-sectional view schematically illustrating an application example of a conventional hydrogen detection tape;
FIG. 3 is a cross-sectional view schematically illustrating an application example of the gas detection element according to the embodiment of the present invention;
In the following, embodiments of the present invention will be described with reference to the drawings.
In the following description, as an application example of an embodiment of the present invention, a gas detection element for detection of hydrogen gas will be described. However, it should be noted that the gas detection element according to the present invention may also be used to detect any reducing gas other than hydrogen gas.
As used herein, the “reducing gas” refers to a gas containing at least one of hydrogen, hydrogen sulfide, carbon monoxide, methane, formaldehyde, acetylene, sulfur dioxide, and nitrous oxide.
