Making method for core component of water-reservation proton exchange film fuel battery

Abstract

The invention relates to a proton exchange membrane fuel cell core module preparation method. The preparation method, its characteristic lies in that it includes the following steps: 1)prepares the proton conduction polymer for decorating an inorganic oxide compound nanometer granule: a) first the weight concentration 1.2% -10% of the proton conductionpolymer solution adjusts with NaOH to the pHvalue 6.5-7.5, then changes over to the anhydrous organic solventin, obtains the solution A, then distills this solution to obtain solution B; b) according to inorganic oxide compound and proton conduction polymerload ratio 0.01: 1-0.1: 1, joins this inorganic oxide compound inorganic oxide compound forerunner body in solution B which prepares in step a) to stir 20-30 minutes, makes the inorganic oxide compound forerunner body solution; c) prepares the proton conduction polymer for decorating an inorganic oxide compound nanometer granule; 2) prepares the fuel cell core module. The guarantee water proton exchange membrane fuel cell core module of the invention preparation has good guarantee water ability.

Description

technical field [0001] The invention relates to a preparation method of a core component of a proton exchange membrane fuel cell. Background technique [0002] Hydrogen is an element ubiquitous in nature and is a renewable and clean energy. Scientists believe that hydrogen energy will make up for and gradually replace the increasingly depleted fossil energy sources such as coal and oil in the 21st century, and become an important part of the world's energy structure. Proton Exchange Membrane Fuel Cell (PEMFC) is an important way to convert hydrogen energy into electrical energy. Its energy conversion efficiency is as high as 50%, and its working temperature is low and its noise is low. The only emission is pure water. , can be widely used in vehicle power source and fixed power station power supply. Therefore, it is generally believed that fuel cells are the preferred clean and efficient power generation technology in the 21st century (Yi Baolian, Fuel Cells—Principles, Te...

Problems solved by technology

Although this method can improve the hydrophobicity of the catalytic layer, PTFE cannot be continuously and uniformly dispersed in the catalytic layer, so it lacks the regulation of water management in fuel cell applications

[0013] However, the core component CCM prepared by these methods has no water retention capacity and is not suitable for working at high temperature or low humidity.
