GDL Substrate
Product Portfolio
Carbon GDL Substrate
Developing GDL substrate for over 30 years
performance GDL substrate, including electrical and thermal conductivity to allow current flow, optimum pore structure for mass transport and mechanical integrity.
Key Properties
Uniform Thickness
Aiding consistent construction of the GDL and manufacturing of the fuel cell.
Controlled Porosity
Tailored pore structure to accommodate different types of carbonaceous filler and post treatments, enabling flexibility in GDL design and processing.
Conductivity
High in-plane & through-plane electrical and thermal conductivity. This enables effective electrical conduction and heat transfer between catalyst and current collector plates to improve cell efficiency.
Chemical Resistance
Excellent chemical and corrosion resistance to reactant gases, this increases cell durability and reduces maintenance.
High Surface Area
Enabling optimum control of reactant gas and water movement during operation, helping to maintain effective mass transport and efficient cell performance.
Durability
Excellent durability & strength, as well as controllable & repeatable compressibility. Ideal for accommodating thickness variation in cell stacks during stack assembly, and adapting to thermal expansion during operation.
Even Surface
An even and consistent fibre distribution provides a suitable architecture for application of smooth microporous layer coating.
Processing
