Embodiment 1

[0135] 2.00 g of 3-acrylamido tetrazole and 0.0293 g of azobisisobutyronitrile were dissolved in 20 ml of DMF (N,N-dimethylformamide). Then, Ar was blown into the mixture to perform gas replacement, and the mixture was reacted at 65° C. for 15 hours under an Ar atmosphere. After concentrating the reaction mixture, it was dropped into methanol, and the precipitate was filtered and dried to obtain a polymer. MW=16000. The structural formula of this polymer is shown below.

Abstract

The present invention is to provide an electrolyte membrane for fuel cell of low fuel permeability and high proton conductivity and to provide a fuel cell comprising the electrolyte membrane. According to the present invention, a polymer membrane including repeating unit of five-membered heterocyclic rings is used as an electrolyte membrane of the fuel cell. The electrolyte membrane has high proton conductivity with free from moves of the fuel or water when the proton conducts in the electrolyte membrane.

Description

technical field [0001] The present invention relates to a proton conductive polymer, a catalyst composition, an electrolyte membrane for a fuel cell, and a fuel cell. Background technique [0002] It is known that proton conductive polymers are useful as functional polymers because they can be used as ion exchange resins or solid acid catalysts. Recently, research on the use of electrolyte membranes using such polymers in fuel cells has been particularly active. [0003] A fuel cell is a system that electrochemically oxidizes fuel such as hydrogen or methanol in the battery, and converts the chemical energy of the fuel directly into electrical energy and takes it out. Since this system does not generate NOx and SOx through combustion of fuel like thermal power generation, it is attracting attention as a clean power supply source. In particular, proton-conducting polymer fuel cells can operate with high efficiency because they are not limited by the Carnot cycle in thermody...
