電気化学的電池用の炭素繊維電極基板

Title:

電気化学的電池用の炭素繊維電極基板

Document Type and Number:

Japanese Patent JP4859334

Kind Code:

B2

Abstract:

This invention relates to electrode substrates for electrochemical cells, particularly low-temperature fuel cells, and processes for their production. Low-cost carbon fiber paper structures are used as precursor for preparation of an all-carbon product that has a high electric conductivity and porosity and can be processed in a continuous reel-to-reel mode. These paper materials are further impregnated and processed to adjust the final product properties. This all-carbon electrode substrate is not brittle thereby avoiding the main disadvantage of the prior art.
