Embodiment

[0036] Such as figure 1 As shown, the embodiment of the present invention provides a low-temperature cold start device for a hydrogen fuel cell engine, which includes:

[0037] The high-pressure hydrogen cylinder 1 is used to provide hydrogen for the heat generator 2 and the hydrogen fuel cell of the hydrogen fuel cell engine 3 . High-pressure hydrogen is stored in the high-pressure hydrogen cylinder 1, which serves as a source of hydrogen for the heat generator 2 and the hydrogen fuel cell. When hydrogen is supplied to the heat generator 2, the hydrogen storage fuel inside the heat generator 2 absorbs the hydrogen to generate heat.

[0038] The first temperature sensor is set inside the hydrogen fuel engine 3, and is used to collect the temperature value of the hydrogen fuel cell in real time, and send it to the controller 4, and the controller 4 determines whether it is necessary to repair the hydrogen fuel cell engine 3 according to the temperature value. for heating.

Embodiment 2

[0057] Such as figure 1 , figure 2 As shown, a low-temperature cold start device for a hydrogen fuel cell vehicle provided by Embodiment 2 of the present invention includes a hydrogen storage container 5 filled with a hydrogen storage alloy or an organic compound hydrogen storage material, and is also provided with a cooling plate Tube (heat transfer coil 6). During the hydrogenation process of the hydrogen storage container 5, the heat generated by the breaking of the H-H bond raises the temperature of the cooling liquid (heat transfer working fluid) in the cooling coil through heat exchange. As the hydrogenation process continues, the temperature of the cooling liquid rises The low-temperature cold start of fuel cell vehicles can be realized at 60-70°C. The hydrogen storage container 5 is provided with a hydrogen port 21 , a safety relief device, a coolant inlet 22 , a coolant outlet 23 and a heat preservation device 24 .

[0058] The hydrogen port 21 of the hydrogen sto...

Abstract

The invention provides a hydrogen fuel cell engine low-temperature cold starting device and method, and belongs to the technical field of vehicle fuel cells, and the hydrogen fuel cell engine low-temperature cold starting device comprises a high-pressure hydrogen cylinder used for providing hydrogen for a heat generator and a hydrogen fuel cell engine; a first temperature sensor used for collecting the temperature of the hydrogen fuel cell engine; a controller which receives the temperature value collected by the first temperature sensor, wherein if the temperature value is lower than a preset first temperature threshold value, an on-off valve of the high-pressure hydrogen cylinder is controlled to be opened, and hydrogen is provided for the heat generator; and a heat generator which stores a hydrogen storage material, wherein the hydrogen storage material receives hydrogen provided by the high-pressure hydrogen cylinder to generate heat for heating the hydrogen fuel cell engine. The heat generator is started under specific conditions, the temperature of the heat transfer working medium in the heat dissipation coil pipe is increased in a heat exchange mode, the temperature of the heat transfer working medium is increased into the fuel cell along with continuous hydrogenation, the temperature of the fuel cell is increased, and low-temperature cold start of the fuel cell automobile is further achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle fuel cells, in particular to a low-temperature cold start device and a start method for a hydrogen fuel cell engine. Background technique [0002] Hydrogen fuel cell is a new generation of green energy power system, which helps to solve problems such as energy crisis and environmental pollution. Driven by technological progress and national policies, hydrogen fuel cell vehicles have gradually achieved mass production. The storage of hydrogen in hydrogen fuel cell vehicles mainly adopts high-pressure storage methods, and there are also methods such as liquid storage and transportation, metal hydride hydrogen storage, and liquid organic compound hydrogen storage. Among them, metal hydride hydrogen storage and liquid organic compound hydrogen storage are two hydrogen storage methods, which release heat during the hydrogenation process and absorb heat during the hydrogen release process.
