Problems solved by technology

However, in the actual test process, hydrogen fuel cell vehicles need to be tested in various types of laboratories such as room temperature drum test chambers, low temperature environment chambers, altitude environment chambers, and electromagnetic compatibility darkrooms. Detect the concentration of hydrogen in the exhaust gas. At present, there is a lack of such a device in the test process that can be applied to hydrogen safety monitoring and hydrogen emission detection of hydrogen fuel cell vehicles in several different test environments.

Abstract

The invention provides a hydrogen detection device of a fuel cell vehicle. The hydrogen detection device mainly comprises a controller, a basic framework, an alarm, a hydrogen safety monitoring sensor and a hydrogen emission detection sensor, wherein the basic framework has a height, length and width adjustable function, so that test demand on vehicles with different sizes is met; the device carries out hydrogen safety monitoring and hydrogen emission detection functions when being used for testing the fuel cell vehicle in a laboratory; and when hydrogen safety concentration exceeds standard, the device can give an alarm by virtue of the alarm. The hydrogen detection device provided by the invention can meet the hydrogen safety monitoring and hydrogen emission detection functions in a test scenario, required by the standard, according to the sizes of different fuel cell vehicles and is simple and reliable in structure and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of automobile safety detection, and in particular relates to a hydrogen detection device for a fuel cell automobile. Background technique [0002] With the development of society, the pressure on the environment is increasing, and various energy-saving and emission-reduction technologies and products are constantly emerging. It is in this environment that hydrogen fuel cell vehicles have developed rapidly. Foreign auto companies such as Toyota, Honda, and Hyundai have already sold commercial vehicles, and domestic hydrogen fuel cell vehicles are also conducting demonstration operations. Since the hydrogen used by hydrogen fuel cell vehicles is a dangerous flammable and explosive gas, it is necessary to monitor the hydrogen concentration in the test environment and test the hydrogen concentration in the exhaust of hydrogen fuel cell vehicles in actual testing. At present, my country's national standard GB / T ...
