Components for electrolysers and fuel cells
Hydrogen from renewable resources is essential for the transition to renewable energy and serves as the foundation for low-emission energy systems. Electrolysers and fuel cells are ideally suited for generating hydrogen or other fuels and converting them into electricity and heat. DLR is presenting its component developments for efficient and cost-effective fuel cells and electrolysers, for example, innovative and long-life platinum-free catalysts. Another key topic is the use of electrochemical and structural methods for characterisation.
Highly stable catalysts for electrolysis and fuel cells using flame spray pyrolysis
Flame spray pyrolysis (FSP) is a versatile and resource-efficient synthesis technique that enables the rapid, scalable production of materials in a single step. Upscaling does not require any changes to the thermal and chemical gradients. Using this technique, DLR has developed a stabilised Pt/C catalyst for PEM fuel cells and an IrySn0.9(1-y)Sb0.1(1-y)Ox solid solution catalyst for PEM electrolysers. These materials are characterised by their exceptional performance and durability, while the amount of precious metal catalyst used in the electrodes has been significantly reduced.
PEMTASTIC: Durable fuel cells for heavy goods transport:
The EU-funded PEMTASTIC research project, supported by the Clean Hydrogen Partnership, is developing long-lasting membrane electrode assemblies (MEA) for heavy-duty applications. Using a model-based design and innovative materials, DLR is optimising durability and performance – even at high operating temperatures above 100 degrees Celsius. This marks an important step towards a sustainable and efficient fuel cell technology. In this project, DLR is collaborating with the following institutions and companies: ZHAW, CEA, Chemours, Imerys, Heraeus, IRD and Symbio.
