摘要： Porous carbon sheets suitable for use as fuel cell electrode support plates are produced by stabilizing acrylic filament precursors through the controlled addition of oxygen thereto. The stabilized filaments are thereafter chopped into short lengths, felted and pressed into sheets with the pressing step being performed at a temperature determined by the oxygen content of the stabilized filaments. The sheets are thereafter pyrolyzed to produce the desired porous substrate material.

摘要： ACRYLIC SYNTHETIC PAPER HAVING AN IMPROVED STRENGTH IS PROVIDED. ACRYLIC POLYMER WAS DISSOLVED AND HYDROLYZED IN A CONCENTRATION NITRIC ACIID TO OBTAIN A POLYMER WITH A SWELLING WATER CONTENT BEING NO MORE THAN 200%; THE THUS HYDROLYZED POLYMER WAS BLENDED WITH UP TO 95% BY WEIGHT OF AN UNHYDROLYZED ACRYLIC POLYMER HAVING AN ACRYLONITRILE CONTENT OF AT LEAST 30% SUCH THAT THE TOTAL ACRYLONITRILE CONTENT IS AT LEAST 60% BY WEIGHT, THEN THE RESULTING BLEND WAS WET SPUN BY NITRILE ACID TO OBTAIN ACRYLIC FIBER; AND FURTHER THE RESULTANT ACRYLIC FIBER WAS BEATEN, COVERTED INTO A PAPER SHEET AND THEN DRIED TO OBTAIN THE ACRYLIC SYNTHETIC PAPER WITH AN IMPROVED STRENGTH.
