Problems solved by technology

When gluing bipolar plates, especially when sticking on some larger planes on some plates, because there is more glue, it will overflow to the surrounding due to extrusion, and it is easy to block the holes on the plates, such as diversion holes or positioning Holes, as well as diversion grooves, affect the normal performance of fuel cells

Embodiment Construction

[0014] Such as figure 1 and figure 2 The fuel cell bipolar plate shown includes two upper and lower plate bodies 1 pasted together. On the pasting surface 4 of the two plates 1, a guide groove 2 and a guide groove passing through the two plate bodies 1 are provided. The orifice 3 and the positioning hole 6, the diversion groove 2 and the diversion hole 3 communicate and are used for circulating the reaction gas, and the positioning hole 6 is used for the installation and positioning of the bipolar plate. In order to prevent the viscose from overflowing and blocking the diversion groove 2, the diversion hole 3 and the positioning hole 6 when pasting the bipolar plate and affecting its normal operation, on the pasting surface 4 of the polar plate body 1, along the diversion groove 2, the diversion hole 3 and the periphery of the positioning hole 6 are provided with a groove 5 to prevent the glue from overflowing. The groove 5 adopts a closed annular structure, and is arranged...

Abstract

The invention relates to a fuel battery dual electrode plate, which comprises the upper and lower adhered electrode plates, whose surfaces have guide grooves and the guide holes through said two electrode plates. The guide groove is connected to the guide hole; the adhesive surface on the electrode plate along the edge of guide groove and hole has the groove to avoid overflow of pastern and jamming the guide groove and the guide hole. After setting the grooves at the edge of guide hole and guide groove, when sticking the electrode plates, the left pastern can flow into the groove by the extrusion to avoid it flowing into guide hole or guide groove in present technique, which will affect the normal operation. The plated pastern can be increased to improve the adhesive reliability and sealing property, improve the pass percent of product, reduce the demand to operator and simplify the operation.

Description

1. Technical field [0001] The invention relates to a fuel cell, in particular to a fuel cell bipolar plate. 2. Background technology [0002] A fuel cell is a device that directly converts the chemical energy of hydrogen and oxygen into electrical energy through an electrode reaction. The biggest feature of this device is that since no combustion is involved in the reaction process, its energy conversion efficiency is not limited by the "Carnot cycle". The efficiency of most types of fuel cells is as high as 50%-60%. With secondary utilization, the total efficiency can be as high as 80%-85%. As a power source, its actual energy utilization efficiency is 2-3 times that of ordinary internal combustion engines. There is almost no pollution during its working process, and its power range is from several watts to several megawatts, and its application range is very wide. There are many types of fuel cells, among which proton exchange membrane fuel cells have the advantages of l...
