Hydrogen sensor for new energy vehicle

Abstract

The invention discloses a hydrogen sensor for a new energy vehicle. The hydrogen sensor for the new energy vehicle comprises a shell, a nonporous gas separation membrane arranged in the shell, a gas detection unit and a humidity regulating-controlling unit, wherein the gas detection unit is located between the gas separation membrane and the humidity regulating-controlling unit; the gas detection unit comprises an electrolyte for carrying out proton transfer, and a working electrode, a counter electrode and a reference electrode which are in contact with the electrolyte, the working electrode, the counter electrode and the reference electrode are all porous gas diffusion electrodes; hydrogen entering into the shell passes through the gas separation membrane by a dissolution-desorption manner, reaches the gas detection unit by a spraying manner, and enters into the working electrode by a vortex manner to generate a chemical reaction. The hydrogen sensor disclosed by the invention is suitable for detecting hydrogen content of environments of new energy vehicle interior and the like, and has the advantages of quick response, strong environmental tolerance, good anti-shock and vibration resistance, excellent selectivity and the like.

Description

technical field [0001] The invention relates to a hydrogen sensor, in particular to a hydrogen sensor for a new energy vehicle. Background technique [0002] With the development of society and the improvement of people's living standards, the number of cars in my country is increasing year by year. While cars bring convenience to people's lives, they also affect people's lives to a certain extent. Traditional automobiles use oil as fuel, and oil is a limited resource. The rapid development of the automobile industry will inevitably bring about the dependence of the national economy on fossil energy and deepen the contradiction between energy production and consumption; Exhaust gas contains many harmful components, such as greenhouse gas carbon dioxide, acid gas sulfur dioxide, highly toxic gas nitrogen oxides, tiny particles that cause smog, and carbon monoxide produced by insufficient combustion. According to statistics, 50% of environmental pollution is caused by emission...

Problems solved by technology

Semiconductor sensors also have the disadvantages of severe drift and attenuation, and are easily affected by ambient temperature and humidity, and must avoid contact with silicone and strong vibration during use.

[0015] In summary, due to the various problems of the current hydrogen sensors, they are not suitable for the emerging field of hydrogen content detection in vehicles, which requires us to develop a sensor suitable for monitoring the hydrogen content in vehicles , to solve the above problems
