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.

Safety Agency Studying Toyota Acceleration Problem

A U.S. safety agency is looking into a consumer's petition alleging that older Toyota Corollas can accelerate unexpectedly at low speeds and cause crashes. The inquiry by the National Highway Traffic Safety Administration covers about 1.69 million of the Corolla compact cars from the 2006 to 2010 model years. The agency will decide whether to open a formal investigation into the problem. An unidentified consumer said in a letter to the agency that he experienced multiple low-speed surges in a 2010 Corolla, and the brakes failed to stop the car in time to prevent a crash. The consumer said the problem caused one collision with a parked vehicle on June 8. "In addition to evidence from our crash incident, we are providing evidence that many other Corolla owners are experiencing similarly unsafe scenarios that are leading to crashes," said a portion of the consumer's letter posted Monday on NHTSA's website. The consumer provided 163 reports from other drivers who experienced a surge at low speed or no speed. But NHTSA said it eliminated duplicates, those outside the scope of the 2006-2010 model years and those from foreign countries to get 141. No injuries were reported. The agency said it would evaluate all of the complaints from the consumer in order to decide whether to grant or deny the petition and open a formal investigation. The consumer filed the petition on Sept. 11, according to the documents. Messages were left Monday morning seeking comment from Toyota. In 2009 and 2010, Toyota issued a series of recalls totaling more than 10 million vehicles for various problems including faulty brakes, sticky gas pedals and ill-fitting floor mats. Toyota is under pressure to announce recalls quickly after a U.S. government investigation found it hid information about past defects. Last month, the company agreed to pay $1.2 billion to settle that investigation. It also paid fines totaling $66 million to the U.S. government for delays in reporting unintended acceleration problems. The company has said it made "fundamental changes to become a more responsive and customer-focused organization, and we are committed to continued improvements."

Toyota FCV rallies to the hydrogen cause as zero car

It's been two decades since Toyota dominated the World Rally Championship with its Celica Turbo 4WD. But this past weekend, Toyota hit the rally stage in a very different vehicle.
That, as you can see, is the Japanese automaker's Fuel Cell Vehicle (FCV), which is still in its prototype phase. We're still at least half a year away from seeing the FCV in production trim, but the model has already been pressed into duty as the "zero car" at the Shinshiro Rally, the last round of the Japanese Rally Championship.
The zero car, for those unfamiliar, is to rally what a pace or safety car is to circuit racing, driving the rally stage to check for signs of trouble before the competitors put their feet to the floor, so it's not as if the FCV needed extensive modifications. From the looks of things, it just needed some jazzy stripes, mud flaps, probably different rolling stock and an interior with racing buckets and harnesses, roll cage, radio equipment and maybe a bit more ground clearance.
