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

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 converts hydrogen and oxidants into electrical energy and reaction products. The internal core component of the device is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode (MEA) is composed of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched between the two sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are even and finely dispersed catalysts for initiating electrochemical reactions, such as metal 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 me...
