Polysulfone based polymer comprising a repeat unit represented by the following Chemical Formula 1 is provided: 

Polysulfone polymers and related polymer electrolyte membranes and fuel cells

The present invention relates to a sulfonated poly(arylene ether) copolymer, a manufacturing method thereof and a polymer electrolyte membrane for fuel cell using the same.

Sulfonated poly(arylene ether) copolymers and related polymer electrolyte membranes and fuel cells

The present invention relates to a multi-layered polymer electrolyte membrane for a fuel cell, which is prepared by introducing an anion binding substance as a coating layer to a non-aqueous polymer electrolyte membrane for preventing the elution of acid, and a fuel cell comprising the membrane. In particular, the present invention discloses a multi-layered polymer electrolyte membrane prepared by coating an anion binding substance on a non-aqueous polymer electrolyte membrane, and a fuel cell comprising the membrane, thereby preventing the elution of acid and maintaining the performance of a fuel cell to economic and environmental profit.

Polymer electrolyte membrane with coating layer of anion binding agent and fuel cell using same

The present invention relates to a polymer blend electrolyte membrane comprising an inorganic polymer having polydimethylsiloxane as a main chain, which has a pore structure at both ends formed by condensation reaction between 3-aminopropyltriethoxysilane and tetraethylorthosilicate, wherein phosphoric acid is chemically linked to an amino group of the pore structure; and a proton-conducting polymer having a cation exchange group at the side chain thereof, as well as a manufacturing method thereof. Generally, proton-conducting electrolyte membranes have significantly reduced ion conductivity at high temperatures. However, proton-conducting electrolyte membranes have advantages in terms of efficiency and cost, and thus it is needed to develop an electrolyte membrane, which has excellent ion conductivity even at high temperature. Accordingly, the present invention aims to provide a polymer blend electrolyte membrane for use at high temperature and a manufacturing method thereof.
