preparation example Construction

[0033] A method for preparing a modified perfluorosulfonic acid composite membrane, comprising:

[0034] The film-forming solution containing metal phthalocyanine and perfluorosulfonic acid is heated to form a film, the metal phthalocyanine includes at least one of copper phthalocyanine, nickel phthalocyanine and cobalt phthalocyanine, the mass ratio of metal phthalocyanine to perfluorosulfonic acid 0.8 to 2:100.

[0035] Specifically:

[0036] Weigh a certain amount of perfluorosulfonic acid stock solution, dilute it with a solvent to a perfluorosulfonic acid solution with a mass fraction of 5%, stir and mix evenly. The solvent used in this step is ethanol, and dilution with ethanol can ensure subsequent film formation.

[0037] Dissolve the metal phthalocyanine in ethanol, stir evenly until the metal phthalocyanine dissolves, then add the metal phthalocyanine solution to the diluted perfluorosulfonic acid solution, mix and stir to obtain a uniform solution to obtain a film...

Embodiment 1

[0043] This example provides a method for preparing a modified perfluorosulfonic acid composite membrane:

[0044] Take 10 g of 20% perfluorosulfonic acid solution by mass and dilute it with ethanol to obtain a solution with 5% perfluorosulfonic acid by mass. 0.02 g of nickel phthalocyanine was dissolved in ethanol to obtain a nickel phthalocyanine solution, and the nickel phthalocyanine solution was added to the diluted perfluorosulfonic acid solution to obtain a film-forming solution.

[0045] Take 10ml of the film-forming solution in a glass petri dish, heat and dry at 100°C to form a film. The mass percent content of nickel phthalocyanine in the composite film is 1%.

Embodiment 2-6

[0047] Examples 2-6 are basically the same as Example 1, except that the heating and drying film-forming temperatures are: 60°C, 90°C, 95°C, 110°C, and 120°C.

Abstract

The invention relates to the technical field of a fuel cell proton exchange membrane and discloses a modified perfluorosulfonic acid composite membrane. The modified perfluorosulfonic acid composite membrane is dispersed with metal phthalocyanine having a mass percentage of 0.8% to 2%, wherein the metal phthalocyanine includes at least one of copper phthalocyanine, nickel phthalocyanine and cobaltphthalocyanine. The composite membrane has good electrical conductivity and thermal stability. The invention also provides a preparation method of the composite membrane above. The method comprises the step of heating a membrane-forming solution containing the metal phthalocyanine and perfluorosulfonic acid to form the membrane, wherein the mass ratio of the metal phthalocyanine to the perfluorosulfonic acid is 0. 8-2:100. The method can prepare the proton exchange membrane with good electrical conductivity and thermal stability. The invention also provides a fuel cell, which comprises the composite membrane above, so that the fuel cell is good in battery performance. The invention also provides an electric appliance. The electric appliance comprises the fuel cell above, so that the electric appliance has good power supply performance.

Description

technical field [0001] The invention relates to the technical field of fuel cell proton exchange membranes, in particular to a modified perfluorosulfonic acid composite membrane and a preparation method thereof, a fuel cell and an electrical appliance. Background technique [0002] With the increasing consumption of fossil fuels worldwide, the demand for clean energy applications is increasing. Hydrogen energy is rich in sources, can be converted efficiently, and has no emission pollution during use. As a carrier of secondary energy, it has important prospects in the fields of industry and transportation. Hydrogen fuel cell vehicles have the advantages of environmental protection, short hydrogenation time, long cruising range, etc., and can be used as clean energy with zero emissions in the true sense of the application. In recent years, the development trend of new energy vehicles has become increasingly strong, and fuel cell vehicles have also received more and more atten...
