We have developed a range of high quality carbon papers (20352F) suitable for use in both stationary and portable fuel cell systems. These materials are designed to meet key GDL criteria and subjected to rigorous testing throughout manufacturing to ensure thickness uniformity and mechanical strength to aid cell assembly. To date our nonwovens have been used extensively within the industry as GDL substrate for proton electrolyte membrane (PEMFC), phosphoric acid (PAFC) and direct methanol (DMFC) fuel cells.
