INRS researchers improve performance of iron-based catalysts

11.08.2011
A breakthrough towards replacing platinum in fuel cells

Having pioneered the development of the first high-performance iron-based catalyst for fuel cells, researchers at INRS recently achieved a second major advance. They developed a new and improved iron-based catalyst capable of generating even more electric power in fuel cells for transportation applications. Previously, only platinum-based catalysts could produce similar performance.

The new research findings from the team of Professor Jean-Pol Dodelet were published in Nature Communications, a prestigious scientific journal part of the Nature Publishing Group. With these new and promising results, we bolster the prospect of iron-based catalysts replacing platinum ones in the electrochemical reduction of oxygen, one of two reactions needed to activate the electric power generator we call a fuel cell. Platinum is rare and very costly, whereas iron is the second most abundant metal on earth and is inexpensive.

"Thanks to this breakthrough we are nearing the day when we will be able to drive electric-electric hybrid vehicles —i.e. battery and fuel cell powered—, which can potentially free us from our current dependence on oil to power our cars," said Professor Dodelet.

Working at the Énergie Matériaux Télécommunications Research Centre in Varennes (Québec), INRS scientists are now focusing on the improvement of the long-term stability (at least 5,000 hours) of these promising new catalysts. "The next step is the most important because it will automatically lead to a high value commercial product, not only for car manufacturers but also for all industrial sectors that use electric power generators or manufacture their components," explained Mr. Dodelet.

About INRS

Institut national de recherche scientifique (INRS) is a graduate and post-graduate research and training university. One of Canada's leading research universities in terms of grants per professor, INRS brings together some 150 professors and close to 700 students and postdoctoral fellows in its centers in Montreal, Quebec City, Laval, and Varennes. Conducting fundamental research essential to the advancement of science in Quebec as well as internationally, INRS research teams also play a critical role in developing concrete solutions to problems facing our society.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
