Abstract

The invention belongs to the field of a fuel cell, and particularly relates to a preparation method of a Pt-Ag / porous polyaniline electrode material. Specific to the shortcomings of limited resourcesand high cost of a Pt catalytic material, the invention provides the preparation method of Pt-Ag / porous polyaniline. Porous polyaniline is prepared by adopting a chemical method, and then a Pt-Ag / porous polyaniline nanocomposite is prepared by adopting an electro-deposition method; electrocatalytic oxidation effects of Pt / porous polyaniline composite electrodes modified by different metals of Fe,Mn and Sn on glycerinum are compared synchronously, and it is determined that the Pt-Ag / porous polyaniline material has the best electrocatalytic oxidation effect on glycerinum; then influence of Pt,and Ag deposition sequences and deposition number of turns on electrocatalytic oxidation of glycerinum are further compared; and it is determined that the best electrode performance of the Pt-Ag / porous polyaniline can be achieved by deposition of Pt first and then deposition of At later at the deposition number of turns of 300. Therefore, the composite fuel has the potential application prospect on the aspect of the fuel cell.

Description

technical field

[0001] The invention belongs to the field of fuel cells, in particular to a method for preparing a Pt-Ag / porous polyaniline electrode material. Background technique

[0002] In recent years, due to reasons such as environmental pollution and energy depletion, the search for new energy sources has become the primary concern of people. As a highly efficient and clean energy technology, fuel cells have promising application prospects. Because direct alcohol fuel cells use liquid alcohols, they have many advantages, such as safety, easy storage and transportation, and low fuel prices, eliminating the cumbersome process of hydrogen reforming. At the same time, because it can directly convert chemical energy into electrical energy without additional charging, as long as the fuel is sufficient, it can continuously generate electrical energy, so fuel cells have very attractive development prospects.

[0003] For the use of direct alcohol fuel cells, methanol fuel i...
