Abstract

The invention relates to a hydrogen fuel cell polymer film and a preparation method thereof. The hydrogen fuel cell polymer film consists of the following components in parts by weight: 12-15 parts of polyaniline, 3-5 parts of triethylene diamine, 2-4 parts of phenylethylene oxide and 8-11 parts of ethyl acrylate. The preparation method comprises the following steps of: dissolving the substances through different solvents, uniformly mixing, then performing reduced pressure distillation to remove the solvents, then soaking in water, and drying to obtain the hydrogen fuel cell polymer film. The hydrogen fuel cell polymer film has a high electron conductivity which is 0.054-0.112S / cm.

Description

technical field [0001] The invention relates to a fuel cell membrane and a preparation method thereof, in particular to a hydrogen fuel cell polymer membrane and a preparation method thereof. Background technique [0002] The performance of the fuel cell has a great influence on the power supply of the battery. In the current research stage, hydrogen fuel cell research is the most vigorous. As a recognized environmental protection and non-polluting energy, hydrogen fuel cell is being vigorously promoted by European and American countries and developing countries. During the application and promotion of hydrogen fuel cells, there are some factors that restrict its promotion. The existence of these factors limits the upgrading of technology and the development of the industry to a certain extent. For example, the membrane that transports ions after fuel decomposition has a great impact on the performance of the battery, and finding a polymer membrane with high electronic cond...
