Abstract

The invention relates to a porous membrane for a hydrogen-chloride fuel battery, as well as a preparation method and application. The preparation method comprises the following steps of: ultrasonically dissolving a macromolecular polymer and nano oxide particles in an organic solvent to prepare membrane production liquid, and preparing a polymer-inorganic porous membrane with an asymmetric morphor structure by adopting a phase inversion method, wherein the thickness of the prepared membrane is 25 to 150 micrometers, and the porous rate is 60 to 80 percent. The thickness, porous rate, aperture and oxide doping volume of the porous membrane prepared by the method are easy to control, the acid retention volume of the prepared membrane is high, the strength is good, the cost is low, the preparation method is simple, and the porous membrane can be well applied to the hydrogen-chloride fuel battery.

Description

technical field

[0001] The invention relates to a porous membrane for hydrogen-chlorine fuel cell using chlorine gas dissolved in hydrochloric acid as a raw material and a preparation method thereof, in particular to a method for directly preparing a hydrophilic porous membrane for hydrogen-chlorine fuel cell by adopting a phase inversion method. Background technique

[0002] Hydrochloric fuel cells use hydrogen as fuel and chlorine as oxidant, and the two undergo electrochemical reactions in the battery, converting the chemical energy stored in it directly into electrical energy, and at the same time can produce hydrochloric acid of required concentration. Therefore, an electrolyte separator is needed to separate the cathode and the anode. Proton exchange membrane (PEM) is one of the core components of proton exchange membrane fuel cell (PEMFC). An ideal PEM should have high proton conductivity, low gas and liquid permeability, high ion selectivity, high enough mechanical s...
