Developments in Fuel Cell Electrode Technology

Technical Fibre Products in partnership with Johnson Matthey Fuel Cells develops a novel and commercially ready electrode substrate for use in fuel cells.

 

The substrate is the result of a collaborative project between TFP and JMFC which has been developed to address the market need for a lower cost alternative to the Gas Diffusion Layer (GDL) materials currently available.

 

The innovation is the output from the project ‘Fuel Cells Incorporating Nanomaterials in Electrode Substrates’ (FINESSE) which has been co-funded by Innovate UK. The project’s primary objective was to develop a novel Membrane Electrode Assembly (MEA) for stationary PEMFC and portable DMFC power applications which delivered similar performance but at a reduced cost. The project incorporated a number of development strands, with TFP leading on the GDL substrate design & manufacture and JMFC leading on coating, MEA consolidation and in-cell testing.

 

According to Technical Fibre Products, their dedicated technology team combines an in-depth understanding of the non-woven forming process with the knowledge and experience to work with a range of fibres, particulates and binders. The application of this expertise has enabled the development of a GDL electrode material which offers comparable properties and performance without the associated high temperature heat treatment techniques which elevate cost.

 

As part of the project, Johnson Matthey Fuel Cells have developed an optimal MEA design which both incorporates the new low cost GDL substrate and simultaneously delivers additional cost savings.  This development of a lower cost electrode substrate and consolidated MEA supports the market need for a cost reduction in fuel cell systems as a whole. Ultimately, making fuel cells a more economically viable green energy source and potentially helping to accelerate market penetration.
