DURABLE MEMBRANE-ELECTRODE ASSEMBLY WITH HIGH IONIC CONDUCTIVITY AND METHOD OF MANUFACTURING SAME

Abstract: disclosed are a membrane-electrode assembly (mea) and a method of manufacturing the same. the mea include an electrolyte membrane and a pair of electrodes, the electrodes being disposed on both surfaces of the electrolyte membrane, respectively. at least one of the electrolyte membranes and electrodes includes an ion-conducting polymer having a proton-conducting functional group, and a compound represented by chemical formula 1 is bonded to each of all or some of the proton-conducting functional groups including the chemical formula 1 of max, wherein m is an element belonging to the lanthanum group, a is a hydrophilic functional group, and x is a numerical value for balance of charges between a and m. since the mea includes an ion-conducting polymer having good chemical durability and proton conductivity, the mea is durable and has high proton conductivity.
