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.
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.

Beyond the limits of conventional electronics: stable organic molecular nanowires

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
