Embodiment 1

[0024] Example 1, see Figure 1-5 , the present invention provides a technical solution: a temperature-controllable fuel cell hydrogen supply and hydrogen return heat preservation heating device, comprising a battery main body 1, a positive electrode joint 12 and a negative electrode joint 13, the upper end of the battery main body 1 is screwed on the right side A threaded joint 2 is connected, a resistance wire 3 is fixedly connected to the lower end of the threaded joint 2, and a heating insulating tube 4 is arranged on the outside of the resistance wire 3, and the heating insulating tube 4 is heated by the resistance wire 3, so that the heating insulating tube 4 can be heated. The pipeline for supplying and returning hydrogen to the fuel cell can be heat-insulated and heated. A connector 5 is fixedly connected to the left side of the upper end of the battery main body 1 , and a thermometer 6 is fixedly connected to the lower end of the connector 5 , and the upper end of the ...

Embodiment 2

[0025] Example 2: see Figure 2-3 , the difference between this embodiment and Embodiment 1 is: the upper end of the thermometer 8 is fixedly connected with a watch cover 17, the middle position of the watch cover 17 is slidably connected with a torsion bar 18, and the lower end of the torsion bar 18 is rotatably connected with a lift rod 19, The surface of the rotating shaft between the lifting rod 19 and the torsion rod 18 is covered with a torsion spring 20. By rotating and pressing the torsion rod 18, the lifting rod 19 can move up and down. The temperature pointer 9 drives the connecting plate 10 to move up and down through the lifting and lowering of the lifting rod 19, which is convenient for the connection of the power supply. The surface of the torsion bar 18 is fixedly connected with a clamping block 21, and the clamping block 21 is slidably connected with the watch cover 17. After loosening, the clamping block 21 is connected with the watch cover 17, so that the tor...

Abstract

The invention relates to the technical field of fuel cells, in particular to a temperature-controllable thermal insulation heating device for hydrogen supply and hydrogen return of a fuel cell, which comprises a cell main body, a positive electrode joint and a negative electrode joint, the right side of the upper end of the cell main body is spirally connected with a screwed joint, and the lower end of the screwed joint is fixedly connected with a resistance wire; a resistance wire is arranged on the upper end of the battery main body, a heating insulation pipe is arranged on the outer side of the resistance wire, and a connector is fixedly connected to the left side of the upper end of the battery main body. Meanwhile, the device can effectively perform heating treatment under the action of the heating insulating pipe, and the arranged heat preservation layer performs heat preservation treatment on the hydrogen supply pipe and the hydrogen return pipe of the fuel cell, so that the fuel cell can be prevented from heat loss after being heated, and the heat preservation temperature of the hydrogen supply pipe and the hydrogen return pipe of the cell can be increased; and heating treatment of hydrogen supply and hydrogen return is facilitated.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a temperature-controllable fuel cell hydrogen supply and hydrogen return heat preservation heating device. Background technique [0002] With the development of society, the application of fuel cells has become more and more extensive. Fuel cells are a chemical device that directly converts the chemical energy of fuel into electrical energy. It is the fourth type of power generation after hydropower, thermal power and atomic power. Power generation technology, because the fuel cell converts the Gibbs free energy part of the chemical energy of the fuel into electrical energy through an electrochemical reaction, which is not limited by the Carnot cycle effect, so the efficiency is high. raw materials, and no mechanical transmission parts, so the emission of harmful gases is very small, and the service life is long. [0003] In the prior art, the fuel cell cannot be effectively ...
