Method for preparing bipolar plate with catalytication

Abstract

This invention relates to a method for preparing aluminum alloy double pole plate with catalytic function for proton exchange membrane fuel cell, that is as follows: take aluminum alloy as the substrate material, use computer carving method for preparation of flow field, carries on superficial modification processing to aluminum alloy through electric deposition of nickel, electric deposition of platinum and combine nickel to form platinum alloy catalyst with the nickel. Advantages: the double pole plate and the catalyst are organically united together to one body, the double pole plate has catalytic effect, reduced battery modules and contact resistance and the enhanced electric contact reliability.

Description

technical field

[0001] The invention belongs to the field of new energy materials, and in particular relates to a preparation method of an aluminum alloy bipolar plate with a catalytic effect for a proton exchange membrane fuel cell. Background technique

[0002] The proton exchange membrane fuel cell has become a hot spot in the research and development of fuel cells due to its outstanding advantages such as low operating temperature, fast start-up, no corrosion, no fear of vibration, high energy density and easy adjustment of output power. The bipolar plate, catalyst and proton exchange membrane three The high price of large components limits the popularization and application of proton exchange membrane fuel cells. At present, bipolar plates are made of carbon plates, graphite-resin, stainless steel and other materials, mainly considering electrical conductivity and mechanical strength, and none of them have catalytic properties. Considering factors such as electrical co...
