SGL Group to develop carbon fibre GDL for EU-funded automotive project

The GDL allows a steady supply of gas to the catalyst layers, which are located on both sides of the ion exchange membrane.SGL Group has become a development partner in the joint development project INSPIRE, that has been funded with a EUR 7 million award from Europe’s Fuel Cells and Hydrogen Joint Undertaking (FCH JU) and will run for three years.

The aim of INSPIRE is to develop a new generation of fuel cells with higher performance and longer lifetime, which will play a major role in the electro-mobility of the future. At the same time, the commercialisation of hydrogen-powered vehicles is set to be accelerated, since they represent an alternative to cars with solely battery-based electric propulsion.

SGL Group is a component developer to the project, and is responsible for the development of the gas diffusion layers (GDL), which will be manufactured based on carbon fibres. The GDL allows a steady supply of gas to the catalyst layers, which are located on both sides of the ion exchange membrane and which convert hydrogen and oxygen into electrical energy and water.

Utilisation of fuel cell technology

“INSPIRE, with high-profile partners from the fields of science and industry, offers an excellent platform to accelerate the utilisation of fuel cell technology with its innovative materials and components,” said Dr Gerd Wingefeld, Chief Technology Officer at SGL Group.

“For SGL Group, it highlights our entrepreneurial claim to play a key role in shaping developments in the megatrends of mobility and energy supply. These include not only graphite anode material for lithium ion batteries and carbon fibre composites for lightweight-construction passenger compartments, but also our gas diffusion layers for alternative drive technologies based on hydrogen.”

Common European supply chain

The project, which kicked-off in May 2016, is being carried out under the coordination of Johnson Matthey, a leading manufacturer of catalyst coated membrane units, as well as other renowned industrial companies such as the BMW Group and Dana Holding Corporation (Neu-Ulm), along with several scientific research organisations (CNRS Montpellier, TU Berlin, TU Munich, University of Freiburg, VTT Espoo) and the SME Pretexo.

In addition to the focus on development, the partners will also be concentrating on establishing a common European supply chain for these critical components; namely the membrane, catalyst, gas diffusion layers and bipolar plates. With this step the capability of serial production will also be demonstrated.
