TFP NONWOVENS - IDEAL GDL PROPERTIES
The properties of our carbon nonwovens fulfil the performance requirements and material characteristics needed from a GDL substrate. These attributes include:
Our veils are highly porous and the pore structure can be tailored to accommodate different types of carbonaceous filler and post treatments.
TFP’s carbon nonwovens have high in-plane & through-plane electrical and thermal conductivity, so effective electrical conduction and heat transfer between the catalyst and the current collector plates can occur.
TFP’s range of carbon mats and veils inherently exhibit good chemical & corrosion resistance to reactant gases.
HIGH SURFACE AREA:
Our materials are highly porous and provide a large surface area. This aids optimum control of reactant gas and water movement during operation, helping to maintain effective mass transport and efficient cell performance.
Our nonwovens provide excellent durability & strength. They exhibit controllable and repeatable compressibility. This is important both in stack assembly to accommodate thickness variation in cell stack components, as well as during operation to adapt to the thermal expansion seen in larger fuel cell stacks.
The superior even fibre distribution characteristic of our nonwovens provides a suitable architecture for application of a smooth microporous layer coating.
