Problems solved by technology

During the working process of the fuel cell, especially in the outdoor working environment, there will be a lot of dust or water that will corrode the stack. Once the dust or water enters the stack, it will cause the stack to leak electricity and hydrogen, and even make the stack Danger of collapse from fatal damage
In the existing fuel cell stack packaging technology, there is no good way to prevent dust and water from entering the stack, and there is no necessary safety protection device for hydrogen leakage

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings.

[0023] Such as figure 1 As shown, a packaging device for a fuel cell stack includes a closed packaging frame 1, which encapsulates all components of the fuel cell integrated stack 2, and the packaging frame 1 is provided with exhaust Port 3, vent 4, and air pipe inlet 5, air pipe outlet 6, hydrogen pipe inlet 7, hydrogen pipe outlet 8, cooling water pipe inlet 9, and cooling water pipe outlet 10 corresponding to the fluid inlet and outlet pipes of the stack; The exhaust port 3 is provided with a hydrogen detector 11, the exhaust port 3 extends outwards with an exhaust pipe 12, and an exhaust fan 13 is provided on the exhaust pipe. There are two exhaust pipes 12, these exhaust The air ducts 12 finally converge into a general exhaust duct 14. The exhaust fan 13 is arranged at the end of the general exhaust duct 14; the vent 4 extends outwards with a ventilation duct 15 on which a blower ...

Abstract

The invention discloses a packing device of fuel battery electric pile, which comprises the following parts: closed-typed sealing rack to seal all components of fuel battery electric pile in the pack, wherein the sealing rack contains vent hole, ventilator and air pipe inlet, air pipe outlet, hydrogen pipe inlet, hydrogen pipe outlet, cooling pipe inlet, cooling water outlet corresponding to each flow inlet pipe, wherein the hydrogen detector is set in the vent hole, which extends a vent pipe outsides; the vent fan is set on the vent pipe; the ventilator extends a ventilating pipe outsides with aerator on the vent hole. The invention can detect hydrogen density to discharge hydrogen disposal timely, which avoids explosion due to hydrogen pipe cracking.

Description

Technical field [0001] The invention relates to a fuel cell, in particular to a packaging device for a fuel cell stack. Background technique [0002] An electrochemical fuel cell is a device that can convert hydrogen and oxidant into electrical energy and reaction products. The internal core component of the device is the Membrane Electrode Assembly (MEA). The Membrane Electrode Assembly (MEA) consists of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched on both sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are uniformly and finely dispersed catalysts that initiate electrochemical reactions, such as metallic platinum catalysts. Conductive objects can be used on both sides of the membrane electrode to draw the electrons generated during the electrochemical reaction through an external circuit to form a current loop. [0003] At the anode end of the membrane electrode, fuel can penetrat...
