Problems solved by technology

[0008] The disadvantages of these technologies are: additional peripheral equipment increases the complexity and power consumption of the entire system, reduces the power density and weight density of the entire system, increases the cost of system operation, and is not conducive to the promotion and use of the technology
The biggest drawback of this technology is: the exchange of blowing and suction directions of the fan requires additional electronic control equipment, which also increases the complexity of the system and additional power consumption

Embodiment Construction

[0024] As shown in Figure 1, a proton exchange membrane fuel cell system designed using the above technology is divided into three layers. The upper layer 1 is an axial fan, the middle layer 2 is a wind shield, and the lower layer 3 is a proton exchange membrane fuel cell stack. .

[0025] The upper layer 1 contains two axial fans, each with a size of 80×80 (mm×mm).

[0026] The middle layer 2 is a transparent plastic windshield for fixing the axial fan and forming a relatively closed space on the upper side of the battery.

[0027] The lower layer 3 is a proton exchange membrane fuel cell stack whose internal structure is shown in Figures 2-6. Figure 2 is the proton exchange membrane electrode; Figures 3 and 4 are the sides A and B of the cathode plate, side A is the linear air guide groove of the cooling unit, and side B is the linear air guide groove of the reaction unit. And the diversion grooves are directly penetrated from one side of the pole plate to the other side; Figure...

Abstract

This invention relates to proton exchange film fuel battery gas supply and cooling system in fuel battery technique field, which comprises outside axis wind motor and matched wind cover and imbedded open air guide tank, wherein, one set of battery is composed of two electrode boards with one as cathode board with A and B surface etched with air conductive tank in line shape; one side of electrode board passes other side with other as anode board with A surface etched with air conductive tank and with B surface etched with enclosed hydrogen air guide tank.

Description

Technical field [0001] The invention belongs to the technical field of fuel cells, and in particular provides an efficient gas supply and cooling system for a proton exchange membrane fuel cell. Background technique [0002] The proton exchange membrane fuel cell is a type of fuel cell. It is a power generation device that directly converts the chemical energy of the fuel (hydrogen) into electrical energy through an electrochemical reaction without burning. [0003] In the proton exchange membrane fuel cell, there is a proton exchange membrane between the anode and the cathode, H + That is, from the anode to the cathode through the proton exchange membrane, and at the cathode with O 2 Combine to produce water molecules (H 2 O). When the battery is high-power output, the current density inside the battery increases, the electrochemical reaction is strengthened, and the water generated on the cathode side will increase accordingly. On the one hand, if the water is not drained in ti...
