Embodiment 1

[0036] In the prior art, since the flow channels on both sides of the bipolar plate do not have the function of adjusting the gas flow, the gas flow of each flow channel is different, resulting in poor performance of the fuel cell.

[0037] To solve the above problems, such as figure 1 and figure 2 As shown, this embodiment provides a bipolar plate assembly. The bipolar plate assembly includes a bipolar plate and an adjustment member 2. The bipolar plate includes a bipolar plate main body 1 and a plurality of flow channel ridges arranged on the bipolar plate main body 1. 12. A delivery groove 11 is formed between any two adjacent flow channel ridges 12, and the delivery groove 11 is used to deliver gas; the regulator 2 is used to adjust the fluid flow rate of the delivery groove 11. The fluid in this embodiment is a reactive gas.

[0038] Specifically, when the bipolar plate assembly is in use, the bipolar plate assembly needs to be used with a membrane electrode. The membr...

Embodiment 2

[0054] This embodiment also provides a fuel cell, including the above-mentioned bipolar plate assembly. The fuel cell also includes a membrane electrode, the bipolar plate assembly includes a bipolar plate main body 1 , and the membrane electrode covers the bipolar plate main body 1 . Due to the inclusion of the aforementioned bipolar plate assembly, it has the advantages of any one of the first embodiment, and realizes the adjustment of the gas flow in the gas channel, thereby ensuring the uniformity of the gas flow in multiple gas channels, so that the gas is fully reaction to improve the performance of the fuel cell.

Abstract

The invention relates to the technical field of fuel cells, and discloses a bipolar plate assembly and a fuel cell. The bipolar plate assembly comprises a bipolar plate and an adjusting piece, wherein the bipolar plate comprises a bipolar plate main body and a plurality of runner ridges arranged on the bipolar plate main body, a conveying groove is formed between any two adjacent runner ridges, and the conveying grooves are used for conveying fluid; and the adjusting piece is used for adjusting the fluid flow of the conveying groove. The fuel cell includes the bipolar plate assembly. According to the invention, the flow of the fluid in the conveying grooves is adjusted, so that the uniformity of the flow of the fluid in the conveying grooves is ensured, and the performance of the fuel cell is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a bipolar plate assembly and a fuel cell. Background technique [0002] A fuel cell is a device that converts chemical energy into electrical energy. The main reactants are hydrogen and oxygen, and the product is only water. It is an environmentally friendly device. The bipolar plate is an important part of the fuel cell, and the two sides of the bipolar plate are used to circulate hydrogen and oxygen respectively. [0003] In the prior art, the flow channels on both sides of the bipolar plate do not have the function of adjusting the gas flow in practical applications, resulting in different gas flow rates in multiple flow channels, resulting in low power conversion efficiency and performance degradation of the fuel cell. [0004] Based on this, there is an urgent need for a bipolar plate assembly and a fuel cell to solve the above-mentioned existing problems. Contents of ...
