Toray Industries, Inc.

Company Information

Toray is diversified corporate group with operations in 18 countries and regions. Underlying our operations is technological expertise in the three core fields of organic synthetic chemistry, polymer chemistry, and biochemistry.

Toray carbon paper has excellent conductivity, shape retaining property and corrosion resistance and is used for a basic material of electrodes of these fuel cells.

We have succeeded in enhancing the capabilities of the membrane electrode assembly (MEA)2) and the polymer electrolyte membrane used in MEA, the primary element in a Direct Methanol Fuel Cell (DMFC)1), to a level where it could be put to practical use. The company for the first time in the world succeeded in developing a hydrocarbon-type membrane that suppresses methanol cross-over (MCO)3) to less than 1/10 of the existing fluorine-type membranes while maintaining the equivalent conductance.
