Embodiment 1

[0053] Get 18.6668 grams of bismaleimidodi-phenylmethane (4,4'-bismaleimidodi-phenylmethane) and place it in a 250ml round-bottomed three-neck bottle, add 50ml of GBL as a solvent, and stir fully after heating to 130°C to make bismaleimidodi-phenylmethane Lyric acid compound was dissolved in GBL. Next, 1.3341 g of barbituric acid (2,4,6-trioxohexahydropyrimidine) was dissolved in 30 g of GBL, and fully stirred to disperse the barbituric acid evenly in the solvent. Next, the solution containing barbituric acid was equally divided into 8 equal parts, and fed into the above-mentioned solution containing bismaleinic acid compound at 130° C. every 30 minutes in batches. After the solution containing barbituric acid was completely added, the reaction was continued for 4 hours. After the reaction is complete, cool to room temperature to obtain hyperbranched polymer (A) (the molar ratio of bismaleic acid to barbituric acid is 5:1, and the solid content is 20 wt%).

Embodiment 2

[0055] Get 20.0002 grams of bismaleimidodi-phenylmethane (4,4'-bismaleimidodi-phenylmethane) and place it in a 250ml round-bottomed three-necked bottle, add 62ml of GBL as a solvent, and stir fully after heating to 130°C to make bismaleimidodi-phenylmethane Lyric acid compound was dissolved in GBL. Next, 3.5752 grams of barbituric acid (2,4,6-trioxohexahydropyrimidine) was dissolved in 32 grams of GBL, and fully stirred to disperse the barbituric acid evenly in the solvent. Next, divide the barbituric acid-containing solution into 4 equal portions, and add it to the above-mentioned bismaleinic acid compound-containing solution at 130° C. in batches every 60 minutes. After the solution containing barbituric acid was completely added, the reaction was continued for 4 hours. After the reaction is complete, cool to room temperature to obtain hyperbranched polymer (A) (the molar ratio of bismaleic acid to barbituric acid is 2:1, and the solid content is 20 wt%).

Embodiment 3

[0057] Get 17.8712 grams of bismaleimidodi-phenylmethane (4,4'-bismaleimidodi-phenylmethane) and place it in a 250ml round-bottomed three-necked bottle, add 50ml of GBL as a solvent, and stir fully after heating to 130°C to make bismaleimidodi-phenylmethane Lyric acid compound was dissolved in GBL. Next, 6.9090 g of barbituric acid (2,4,6-trioxohexahydropyrimidine) was dissolved in 30 g of GBL, and fully stirred to disperse the barbituric acid evenly in the solvent. Next, the solution containing barbituric acid was equally divided into 8 equal parts, and fed into the above-mentioned solution containing bismaleinic acid compound at 130° C. every 30 minutes in batches. After the solution containing barbituric acid was completely added, the reaction was continued for 4 hours. After the reaction is complete, cool to room temperature to obtain hyperbranched polymer (A) (the mol ratio of bismaleic acid to barbituric acid is 1:1, and the solid content is 20 wt%).

Abstract

The invention relates to a proton exchange membrane with high proton conductivity. The proton exchange membrane comprises at least one organic polymer base material capable of conducting protons and a macromolecule with a high branched structure; and the macromolecules of two patterns are evenly mixed, wherein the high branched macromolecule accounts no less than 5% of the integrated solid content of the proton exchange membrane. The high-temperature electrical conductivity of the proton exchange membrane reaches 0.1S / cm@ 100DEG C / 100%RH, and the normal temperature electrical conductivity of the proton exchange membrane reaches 0.03 S / cm@ 25DEG C / 100%RH.

Description

technical field [0001] The invention relates to a proton exchange membrane, in particular to a proton exchange membrane which can operate at high temperature. Background technique [0002] A fuel cell (Fuel Cell, FC) is a power generation device that uses chemical energy to be directly converted into electrical energy. Compared with traditional power generation methods, fuel cells have low pollution, low noise, high energy density, and high energy conversion efficiency. The advantage is that it is a very future-looking clean energy, which can be applied in various fields such as portable electronic products, household power generation systems, transportation tools, military equipment, space industry, and large-scale power generation systems. The operating principle of fuel cells varies slightly depending on the type. Taking Proton Exchange Membrane fuel Cell (PEMFC) as an example, hydrogen undergoes an oxidation reaction in the anode catalyst layer to generate hydrogen ions ...
