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.

Future Classics, Acura Integra Type S and Cadillac Escalade-V | Autoblog Podcast #759

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. They jump right in with some news that Toyota may revive the Land Cruiser in the U.S., followed by rumors of a Nissan GT-R successor. From there, it's on to official confirmation of the Acura Integra Type S revival, followed by a partial rundown of Hagerty's 2023 Bull Market List. After that, it's time for some road test updates. Greg talks about his time in Autoblog's long-term BMW 330e PHEV and contrasts it with the 2023 Cadillac Escalade-V. Byron has been driving a Nissan Rogue, Mazda CX-30 and an Infiniti Q50 — serving as a perfect launch pad for a look back at 2022's best sport sedans. After that, it's a preview of Autoblog's 2022 Holiday Gift Guide.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

Despite slow sales, no new Scion models in near-term pipeline [w/poll]

According to a top Toyota executive, the Japanese automaker will not be introducing any fresh Scion models in the near future, Reuters reports. As of August, Scion sales for this year were down 1.6 percent from 2012 and accounted for only 0.3 percent of Toyota's overall US sales. And last month, Toyota Motor Sales USA Senior Vice President Bob Carter informed the 1,000 dealers who carry Scion that they can drop the brand without penalty.
However, never fear - Carter has assured that, while nothing new is coming for at least six months, the company is still very committed to the quirky Scion brand. Toyota launched Scion, which targets the youth market, in 2003, and sales peaked in 2006. The brand currently has five models, with the 2013 best-sellers being the FR-S sports coupe followed by the tC sedan and xB hatchback.
What do you think about Toyota's decision to hold off on introducing new or refreshed Scion models? Are they heading in the right direction, or does this spell doom for the funky Gen Y brand?
