Problems solved by technology

However, in the fuel cell environment, the reactant and product water, and the cooling fluid have a certain corrosive effect on the gold layer; and the combination of the gold layer directly plated on the base of the collector plate such as stainless steel and aluminum and the base of the collector plate Relatively poor resistance, which will lead to poor anti-corrosion performance of this kind of collector plate

Embodiment Construction

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

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

[0033] see figure 1 , first provide a current collector base 10 . The specific steps are:

[0034] Firstly, a metal plate such as a brass plate, stainless steel plate or aluminum plate is provided, which is machined into a prototype of the current collector plate, that is, the base 10 of the current collector plate. At least one surface of the current collector plate base 10 is formed with a plurality of guide grooves 12 for the entry and exit of fuel cell reactants, products and cooling fluid. In this embodiment, a single surface of the current collector plate base 10 has a guide groove 12, which can be used as an outer current collector plate for a fuel cell. Of course, flow guide grooves can also be...

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...
