Abstract

The invention relates to a hydrogen sensor. The hydrogen sensor is characterized in that by oxidizing and burning to-be-tested gas that is blown in, current gas concentration index to be measured is obtained; the sensor can allow users to know more about the concentration of the to-be-tested gas so that current practical actions are determined. The hydrogen sensor has the advantages of preventingsuch substances as moisture or oxygen absorbed by a substrate from impregnating a film layer with a protective film formed between the substrate and the film layer of a test device, prevent a catalystlayer from absorbing such substances as moisture or oxygen in the environment with the protective film formed on the surface of the catalyst layer, and thus preventing deterioration of the film layerand the catalyst layer.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a hydrogen sensor. Background technique [0002] Hydrogen, together with solar energy and nuclear energy, is known as the three major new energy sources due to its high combustion efficiency and non-polluting products. As a new energy source, hydrogen is widely used in aviation, power and other fields; at the same time, as a reducing gas and carrier gas, hydrogen plays an extremely important role in chemical industry, electronics, medical treatment, metal smelting, especially in the field of military defense. Value. However, hydrogen molecules are very small, and are easy to leak during production, storage, transportation and use. Since hydrogen is not conducive to breathing, it is colorless and odorless, and cannot be detected by the human nose, and its ignition point is only 585°C. In the range of 4% to 75%, it will explode when it encounters an open flame. Therefore, in the use of hyd...
