Embodiment Construction

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0030] As a first aspect of the present invention, a cooling plate is provided. Such as Figures 1 to 5 As shown, the cooling plate includes multiple cooling channels 10 , and the coolant inlets 11 of at least two cooling channels 10 in the multi-channel cooling channels 10 are set in the local reaction high temperature zone 20 . Since there are multiple cooling channels 10, the coolant inlets of the multiple cooling channels 10 can be correspondingly provided in the local reaction high temperature zone 20 according to the reaction conditions of the fuel cell 100, thereby controlling the local reaction high temperature zone of the fuel cell 100. Targeted multi-point cooling is performed to ensure the water content of the proton exchange membrane, t...

Abstract

The invention provides a cooling plate, a fuel cell and a fuel cell system. The cooling plate comprises a plurality of cooling runners, wherein coolant inlets of the at least two cooling runners of the cooling runners are formed in a local reaction high temperature region. Since the cooling runners are arranged, the coolant inlets of the cooling runners can be correspondingly formed in the local reaction high temperature region according to a reaction situation of the fuel cell, specific multipoint cooling is performed on the local reaction high temperature region of the fuel cell, a water content of a proton exchange membrane is ensured, the current density stability and overall electric energy efficiency of the fuel cell are ensured, and the service life of the fuel cell is ensured. At the same time, the cooling plate has the characteristics of simple structure and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of fuel cells, and more specifically, to a cooling plate, a fuel cell and a fuel cell system. Background technique [0002] A fuel cell is a power generation device that converts chemical energy into electrical energy in a non-combustion manner. It has the advantages of environmental friendliness, safety, reliability, and ease of operation. Since the fuel cell is not limited by the Carnot cycle, its direct power generation efficiency can reach 45%, and its combined heat and power efficiency can reach more than 90%. It is widely used in many fields such as backup power supply, distributed power station and automobile power. There are many types of fuel cells, among which proton exchange membrane fuel cells have the advantages of high current density, high power generation efficiency and rapid start-up at room temperature. [0003] In a proton exchange membrane fuel cell, a solid polymer proton exchange membr...
