Abstract

The invention relates to a ventilation and package method of a fuel cell galvanic pile, which comprises a closed package frame. All components of the fuel cell galvanic pile are packaged in the package frame; a ventilation opening is arranged on one surface of the panel of the closed package frame; the ventilation opening is connected with the air blower outlet of the air supplying device of the fuel cell galvanic pile; an air outlet is arranged on the other surface of the panel of the closed package frame; the air outlet is provided with a hydrogen detector which can detect the concentration of the hydrogen inside the closed package frame of the fuel cell galvanic pile. Compared with the prior art, the invention has the advantages that the structure is simple, dust and water can be effectively prevented, the hydrogen concentration can be timely detected, and hydrogen discharging treatment can be timely performed, thereby the explosion caused by the leakage of the hydrogen in the fuel cell galvanic pile can be effectively prevented.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a method for ventilating and encapsulating 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...
