Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example (b):
as shown in fig. 1-2, a spray-molded composite proton exchange membrane comprises a proton exchange membrane 1, wherein support membranes 2 are arranged on two sides of the proton exchange membrane 1; the proton exchange membrane 1 comprises an exchange membrane main body 101, wherein the two sides of the exchange membrane main body 101 are provided with nanometer membranes 102, and the inner sides of the nanometer membranes 102 are provided with filling materials 103; the support film 2 is formed by weaving a plurality of groups of vertical ribs; utilize support membrane 2 to support proton exchange membrane 1, prevent that proton exchange membrane 1 from causing the membrane body to damage because of the bending when using, utilize support membrane 2 to strengthen the intensity of toughness, improve life to proton exchange membrane 1.
As shown in fig. 2, the nano-film 102 is provided with micro-holes at positions corresponding to the filling material 103; the filling material 103 is an oxidized platinum noble metal material; due to the characteristics of small nano-particle size and large specific surface area of the nano-film 102, the water retention capacity of the composite film is improved, and the platinum after being subjected to peroxide can keep high-strength activity and increase the exchange rate of positive hydrogen ions.
The working principle is as follows: when this kind of spraying shaping composite proton exchange membrane uses, increase proton exchange membrane 1's holistic toughness strength through supporting membrane 2, make proton exchange membrane 1 can not be impaired problem because of the bending when using, this proton exchange membrane 1 is working simultaneously, because added nanometer membrane 102, because nanometer membrane 102 itself has the characteristics that nanoparticle size is little and specific surface area is big and makes the water holding capacity of membrane itself promote, and through filler material 103 established in nanometer membrane 102, filler material 103 can be the platinum noble metal material after the oxidation, platinum noble metal after the peroxide can keep the activity of platinum, thereby the exchange rate of positive hydrogen ion has been improved, fuel cell's energy conversion efficiency has been improved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
