Disclosed are a highly durable electrolyte membrane having improved ion conductivity and a method of producing the same. The electrolyte membrane may include an ionomer having hydrogen ion conductivity and a complex dispersed in the ionomer. The complex may include: a support; a primary antioxidant loaded on the support and having radical scavenging ability; and a secondary antioxidant loaded on the support and having peroxide decomposition activity.

Highly durable electrolyte membrane having improved ion conductivity and production method therefor

Disclose is a method of manufacturing catalyst ink for a fuel cell, and particularly the method includes removing eluted transition metal from a noble-metal/transition-metal alloy catalyst.

Method of manufacturing catalyst ink free of eluted transition metal for fuel cell

Disclosed is a method of manufacturing a membrane-electrode assembly for fuel cells. The method includes (a) admixing a metal catalyst, an ionomer and a first dispersion solvent to prepare a first admixture, (b) heat treating the first admixture prepared in (a) to form an ionomer-fixed metal catalyst, and (c) immersing the ionomer-fixed metal catalyst formed in (b) in a solvent, wherein the solvent in (c) may include one or more selected from the group consisting of ethanol, propanol, and isopropyl alcohol. The membrane-electrode assembly for fuel cells manufactured by the method may have substantially improved durability.

Method of manufacturing membrane-electrode assembly for fuel cells

A method for manufacturing a fuel cell electrode includes forming a first mixture by mixing a first cation exchange resin, a metal catalyst, and a first solvent, powderizing the first mixture to produce a first catalyst powder comprising the metal catalyst coated with the first cation exchange resin, forming a second mixture by mixing the first catalyst powder, a second cation exchange resin, and a second solvent, powderizing the second mixture to produce a catalyst powder having a core and two or more layers of shells and being coated with the second cation exchange resin, mixing the catalyst powder having the core and two or more layers of shells with a third solvent to produce a catalyst slurry, and coating, using the catalyst slurry, to produce an electrode.

Methods for manufacturing fuel cell electrodes and electrodes formed using the same

A manufacturing system and method of an membrane electrode assembly (MEA) for a fuel cell is provided which increases performance and durability of an MEA and ensures productivity of the MEA therein. In particular, electrodes and an electrolyte membrane are bonded together and the membrane electrode assembly manufactured in the bonding process is pressed at a predetermined temperature.
