Example Embodiment

[0031] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The manufacturing method of the collector plate provided by the first embodiment of the present invention includes the following steps:

[0033] See figure 1 , First, a collector plate base 10 is provided. The specific steps are:

[0034] First, a metal plate such as a brass plate, a stainless steel plate, or an aluminum plate is provided, which is machined into a prototype of the collector plate, that is, the collector plate base 10. A plurality of diversion grooves 12 are formed on at least one surface of the collector plate base 10 for the in and out of reactants, products, and cooling fluid for the fuel cell. In this embodiment, a single surface of the collector plate base 10 has a flow guide groove 12, which can be used as an outer collector plate for a fuel cell. Of course, it is also possible to form flow guide grooves on opposit...

Abstract

This invention relates to a collecting board including: a collecting board matrix, a Ni layer on the surface of the board and a golden layer on the surface of the NI layer, in which, said board is a metal material matrix, one Ni layer is formed on the matrix then a golden layer on the Ni layer. Since the Ni layer has good anti-corrosion effect and very well combined with the matrix and the golden layer with good conductivity and small contact resistance.

Description

【Technical field】 [0001] The invention relates to a collector plate for a fuel cell and a manufacturing method thereof. 【Background technique】 [0002] A fuel cell is a device that converts chemical free energy directly into electrical energy. It uses non-petroleum fuels such as hydrogen, natural gas, coal gas, and methanol to react electrochemically with pure oxygen or air at the two poles of the battery to continuously provide DC power to the load. [0003] Proton exchange membrane fuel cell is a kind of fuel cell. Its working principle is to provide hydrogen-containing fuel and oxidant at the anode and cathode of the battery respectively, and use the two poles to continuously undergo electrochemical reactions to generate current. [0004] For proton exchange membrane fuel cells, it is a multilayer structure. The middle layer of a single fuel cell is an electrolyte membrane that transports protons, also known as a proton exchange membrane. Located on both sides of the p...
