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 recalling small number of 2014 FJ Cruisers for possible steering failure

Toyota is issuing a fairly tiny recall to fix a potentially serious problem in the FJ Cruiser. The company is recalling about 120 examples of the rugged SUV from the 2014 model year because the steering can fail. According to Toyota, the intermediate shaft that connects the steering wheel and steering gear box might not be welded correctly and can separate. If this happens, drivers lose steering control, which is obviously a major safety concern. However, the automaker is not aware of any crashes, injuries or fatalities from the problem. On the small number of affected models, Toyota will replace the intermediate shaft with a new one. TOYOTA RECALLS CERTAIN 2014 MODEL YEAR FJ CRUISER VEHICLES TORRANCE, Calif., February 5, 2015 – Toyota Motor Sales, U.S.A., Inc., today announced it will conduct a safety recall of approximately 120 Model Year 2014 FJ Cruiser vehicles. The steering system contains an intermediate shaft, which connects the steering wheel to the steering gear box. In the involved vehicles the intermediate shaft could have received an inadequate weld. Under some circumstances, the weld could separate, resulting in the loss of steering control and increasing the risk of a crash. Toyota is not aware of any crashes, injuries, or fatalities caused by this condition. Owners of the involved vehicles will receive a notification by first class mail. Toyota dealers will replace the intermediate shaft. Detailed information is available at www.toyota.com/recall and by calling Toyota Customer Service at 1-800-331-4331.
