Toyota claims hydrogen fuel cell breakthrough

Platinum isn't cheap. And it's a necessary component of hydrogen fuel-cell technology. Which means that Toyota's recent discovery of a way to better analyze how platinum breaks down is a bit of an H2 vehicle breakthrough. Toyota worked with the Japan Fine Ceramics Center (JFCC) to observe nanometer-sized platinum particles and, specifically, how they deteriorate. Platinum is used as a catalyst for when electrons are stripped away from the hydrogen molecule to create an electrical charge and when hydrogen ions and electrons mix with oxygen to create water vapor. So, when platinum gets more course during the countless chemical reactions inside of fuel cells, things slow down. Now that Toyota says it's figured out a better way to observe this process, greater efficiency and durability within the fuel-cell process of electricity production are likely to follow, though more chemistry study will be needed to figure out how that will work. Still, it's topical because Toyota last year started producing the world's first production hydrogen fuel-cell vehicle. The Japanese automaker debuted sales of the Mirai fuel-cell vehicle in Japan late last year and plans to start selling the car in California this fall (the car will be priced at $57,500). Toyota also plans to boost Mirai production to about 2,000 units in 2016 from about 700 this year. Take a look at Toyota's documents and video below. R&D Breakthrough Sets Stage for More Efficient, Durable Fuel Cell Stacks Toyota City, Japan, May 18, 2015—A breakthrough in the real-time observation of fuel cell catalyst degradation could lead to a new generation of more efficient and durable fuel cell stacks. Toyota Motor Corporation and Japan Fine Ceramics Center (JFCC) have developed a new observation technique that allows researchers to monitor the behavior of nanometer-sized particles of platinum during chemical reactions in fuel cells, so that the processes leading to reduced catalytic reactivity can be observed. Platinum is an essential catalyst for the electricity-producing chemical reactions occurring between oxygen and hydrogen in fuel cell stacks. Reduced reactivity is the result of "coarsening" of platinum nanoparticles—a process whereby the nanoparticles increase in size and decrease in surface area. Up until now, however, it has not been possible to observe the processes leading to coarsening, making it difficult to analyze the root causes.

The tumultuous history of the diesel engine

Volkswagen, diesel's most enthusiastic patron, deceived everyone about the amount of emissions its cars were putting out. We have covered this latest massive automotive scandal in great detail, and there are surely more fascinating revelations to come. It turns out that this is just the latest episode in the epic story of the controversy and intrigue surrounding the diesel engine, and its inventor. This is the story of the tumultuous birth and interesting evolution of the compression-ignition engine at the center of the VW scandal. Napoleon III Got Rudolf Diesel Deported Rudolf Diesel was born in Paris in 1858. His Bavarian parents had settled in France where his father, Theodor, was a leather goods manufacturer. When the French Parliament declared war on Prussia, kicking off the Franco-Prussian war, the Diesels fled to London. When he was 12, Rudolf went to live with his aunt and uncle in the Bavarian university town of Augsburg. It was his parents' hometown, and importantly, it's where Rudolf began studying at the Royal County Trade School. His time in Augsburg, graduating at the top of his class from trade school that laid the groundwork for all that was to come. Diesel Nearly Blew Himself Up An early career in refrigeration saw Diesel running R&D in Berlin for Linde, a company started by refrigeration pioneer Carl Von Linde, one of Diesel's professors. His ambition to branch out beyond refrigeration, and his deep understanding of thermodynamics, led to efficiency experiments with steam engines. Diesel was trying to create an engine that didn't waste heat from the combustion process, therefore getting the most work out of the fuel. Instead, he was nearly killed when an experimental ammonia vapor steam engine exploded. Recovery took many months, and during some of that time, he was no doubt planning his next experimental engine, based on the theoretical Carnot cycle. His Engine Was An Attempt To Stick It To The Man Steam engines were expensive to run and wasteful. Diesel thought the efficiency of his design would be a way for the small business to compete with the dominant industrial giants. It was, and it did, but big business is equally passionate about chasing efficiency. Diesel engines quickly proliferated in industries both grand and cottage. Rudolf Didn't Really Invent The Diesel As We Know It Instead, he improved an existing one to a significant degree. The Diesel engine could be considered an evolution of the "hot-bulb" engine.

Scion testing updated FR-S

It looks like Toyota is preparing a mid-cycle update for its critically acclaimed GT86, known here in the US as the Scion FR-S or Subaru BRZ. As far as updates go, this one looks to be rather average. Hidden behind the camouflaged front and rear ends, we have new headlights and taillights, which according to our spies looked to be of the LED variety. We wouldn't be shocked to see the GT86 get LED taillights, although fitting the top-of-the-line headlights seems less likely. Supporting that position are the images we have of the actual headlights in action, which don't look quite bright enough to be full LED units. Instead, we'd expect some new form of running light, perhaps with bi-xenon low beams. Aside from the lamps, the front bumper gets a larger, more prominent lower intake, while the rear end sports a redefined bumper that houses larger dual exhaust tips. The size of the spoiler has been increased, too. According to our spies, we should also expect powertrain enhancements – which we can only hope means more power – as well as upgrades to the interior of the GT86. While it's possible that the updates being tested in Germany could be exclusive to the European market, that seems unlikely. We'd expect the same new enhancements to at least find their way to the Scion, if not its Subaru-badged twin. Check out the full battery of spy photos up top. Related Video:
