CARBON FIBER ELECTRODE SUBSTRATE FOR ELECTROCHEMICAL CELLS |
摘要 |
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 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. |
