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.

Toyota JPN Taxi Concept is a Japanese riff on an English classic

As far as beasts of burden go, New York City's new - and much maligned - Nissan NV200 "Taxi of Tomorrow" isn't a bad one. It's space efficient, reasonably economical, and its simple construction should mean it's pretty robust over the long haul, too. But it lacks panache and a sense of occasion - let alone a sense of humor - three things this this Toyota JPN Taxi Concept we found at the Tokyo Motor Show has in spades.
Unfortunately, that's about all the information we have on this cheeky London-taxi-inspired showcar. Toyota hasn't provided much in the way of details, other than to proclaim that the five-seat JPN was "created with Japanese hospitality in mind" and it "aims to enliven city streets." Japan's livery landscape has long been occupied by traditional three-box sedans - models like the Toyota Crown and Nissan Cedric. The JPN Taxi at just over 171 inches would appear to offer both a tighter footprint and added whimsy, both of which are in the automaker's favor; we hear it hopes this concept will one day become the country's own version of America's yellow Crown Vic cab.
Toyota isn't providing powertrain specifications, but we like the airy feeling of the interior (Japanese cabs typically don't have cumbersome partitions between cabbie and passengers), the minimalist driver area with three screens, and the widescreen overhead video system for passengers that bookends the panoramic moonroof.

Toyota builds its 500,000th Corolla in Mississippi

Toyota assembles the Corolla at plants around the world: from Brazil and South Africa to Turkey, Pakistan, China, Taiwan and Thailand. But the one we get here is built in Mississippi, and that location has just finished its 500,000th Corolla. The plant in Blue Springs, MS, is just one of a half-dozen assembly plants Toyota operates in the United States, but reached the half-million mark faster than any of the others. It began production late in 2011 and took over Corolla assembly from the NUMMI plant in California previously operated via joint venture with General Motors and now occupied by Tesla. Last year, the 2,000 workers at Toyota Motor Manufacturing Mississippi built 180,000 Corollas, contributing to the 10 million units of the model Toyota has sold in America since it was introduced here in 1968 and the 21 million vehicles Toyota has made in America over the years. 500,000th Corolla Speeds Off the Line at Toyota Mississippi Blue Springs plant celebrates milestone achieved at record pace BLUE SPRINGS, MISS. (Feb. 12, 2015) – Toyota Mississippi is celebrating the 500,000th Corolla coming off the line at the Blue Springs, Miss., production facility. The production accomplishment was achieved faster than any other Toyota plant in the U.S. – a testament to the 2,000 hardworking team members who have answered increasing consumer demand since the plant opened in 2011. "The 500,000th Corolla vehicle is a milestone we're excited to be celebrating," said Fred Volf, Toyota Mississippi, vice president of manufacturing. "We are proud to produce the Corolla, and it wouldn't have been accomplished without the 2,000 dedicated team members who support this operation." The milestone is one more to add to the long list of achievements for Toyota Mississippi and the Corolla. Toyota has sold more than 10 million Corollas in the U.S. and 40 million worldwide since the vehicle debuted here in 1968. The success of Corolla contributes to Toyota's accomplished domestic manufacturing footprint and represents Toyota's commitment to producing vehicles where they are sold. Since 1986, more than 21 million Toyota vehicles have rolled off the line in the U.S. and including dealers and suppliers, Toyota has generated 365,000 U.S. jobs. Toyota's local presence is felt by those in Northeast Mississippi through substantial economic investment, employment, philanthropic efforts and environmental responsibility.
