Uses in fuel cells sought for cup-stacked CNTs

GSI Creos plans to accelerate its development of carbon nanotubes (CNTs) for fuel cell applications by focusing on the use of its cup-stacked CNTs (CSCNTs) in the membrane electrode assembles of polymer electrolyte fuel cells (PEFCs). 

The company's Carbere line of CSCNTs comprises cup-shaped CNTs stacked without bottoms to control diameter and length, while allowing treatment of the cups' surfaces. 

Carbere CSCNTs also have a highly crystalline structure for improved conductivity. GSI hopes to position its CSCNTs as an alternative carbon material in PEFCs. 

The company plans to initially use the CSCNTs as catalyst carriers due to their high catalytic reaction efficiency.
