Embodiment Construction

[0024] The embodiment shown in the drawings is a 15kW fuel cell stack for vehicles, which is composed of a non-conductive end plate 1, a metal bipolar plate 3, and a current collector plate 2. The side of the end plate 1 is provided with an air inlet and outlet 5, a hydrogen inlet and outlet 6, and Auxiliary cooling water inlet and outlet 4. The effective area of ​​the battery is 360 square centimeters, the number of battery cells is 120, and the current density is 500 mA per square centimeter. Use the end plate 1, metal bipolar plate 3 and collector plate 2 of the fuel cell of the prior art to assemble the fuel cell stack, keep the shape of each plate unchanged, and keep the inlet and outlet 4 of the heat dissipation water, so that it can meet the needs of natural heat dissipation. When the heat dissipation of the whole vehicle is required, it is used as an auxiliary heat dissipation. The outer surface of the fuel cell outer package 7 is provided with finned heat sinks. The ...

Abstract

The invention relates to a wind-radiating vehicular fuel cell, comprising a fuel cell stack formed by a plurality of sections of monocells; the fuel cell stack is compactly fixed by an end plate; the external package of the fuel cell is fixedly connected on the end plate of the fuel cell stack; the outer surface of the external package of the fuel cell is provided with radiating fins which are distributed parallelly to the moving direction of a vehicle; the inner surface of the external package is coated with heat-conducting rubber in an attached manner; and the surface of the heat-conducting rubber is connected with double polar plates of the fuel cell stack in a leaning manner. The wind-radiating vehicular fuel cell has the advantages that: the outer surface of the external package of the fuel cell stack is provided with the radiating fins, so as to lead the external package of the fuel cell stack to be firmer, thus leading the assembly of the external package of the fuel cell stack to be more strong and firm; and the wind-radiating vehicular fuel cell also can save the energy, reduce radiating devices, optimize the system, improve the reliability, and can reduce the cost, thus being beneficial to realizing the commercial application of the fuel cell.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to the heat dissipation technology of fuel cells. Background technique [0002] In the prior art, the heat dissipation of the vehicle fuel cell is to rely on the cooling water system of the fuel cell to cool most of the heat generated by the internal reaction of the fuel cell; . The disadvantages of the prior art are: the heat dissipation effect of the outer packaging surface of the fuel cell is poor, and an additional heat dissipation device needs to be added, which not only wastes energy but also increases weight and cost. Contents of the invention [0003] The object of the present invention is to provide a fuel cell for vehicles that utilizes the outer package of the fuel cell to dissipate heat. [0004] The technical solution of the present invention is: a wind-heated vehicle fuel cell, including a fuel cell stack composed of multiple single cells, the fuel cell stack is...
