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.

Ex-Toyota Bill Reinert still in favor of hybrids, against EVs

Former Toyota executive Bill Reinert is so unsold on electric vehicles as a viable advanced-powertrain option for future transportation that he has praised – gasp – Ford, for its downsized internal combustion engines. Reinert was a key player in developing Toyota's original Prius hybrid and, in an interview published in Yale University's Environment 360 blog, said a hybrid that gets 60 miles per gallon is superior to an electric vehicle. "And that is why you will be seeing more fuel cells in the future." – Bill Reinert Reinert went on to praise the advances that automakers have made in improving fuel economy of fossil fuel vehicles, specifically namechecking Ford and its three-cylinder Ecoboost engine. He also has good things to say about both hydrogen fuel-cell electric technology as well as natural gas vehicles, but admits that limited fueling infrastructure will keep those types of vehicles in the margins for the near future. He also says that hydrogen vehicles aren't that great yet but that, "When most [manufacturers] investigate the two technologies [H2 and EVs], they see that FVCs offer more room for performance improvement and cost reduction potential. And that is why you will be seeing more fuel cells in the future." As far as pure electric, Reinert says lithium-ion batteries have "tremendous shortcomings" and talks about battery degradation, substandard performance in hot weather and, of course, limited single-charge driving range. He also says that people need to factor in the environmental impact of producing electricity for the grid to fully gauge how environmentally beneficial EVs can be. We'd like to take him and Tesla Motors Chief Elon Musk to what we think would be a spirited lunch. You can read the whole interview with Reinert here.

Senator pushes for up to life sentence for auto execs found to delay recalls

Democratic Senator Claire McCaskill (shown above) has had it with automotive execs stalling when it comes to recalls. The Missiourian has proposed a new bill, the Motor Vehicle and Highway Safety Enhancement Act, which aims to improve the automotive safety following the high-profile fiascos involving General Motors and Toyota. Aside from a doubling of the budget for the National Highway Traffic Safety Administration over the next six years and the removal of the $35-million limit for fining automakers, the plan includes a provision that would punish auto executives if it's discovered they knowingly delayed recalls. How will it punish them, you ask? Oh, you know, just life in prison. The bill "gives federal prosecutors greater discretion to bring criminal prosecutions for auto safety violations and increases the possible penalties, including up to life in prison for violations that result in death," McCaskill's office told The Detroit News. If a delayed recall led to serious injuries, meanwhile, execs could still face a 15-year stint behind bars. As for that change in the fine structure for automakers, the removal of the limit is complemented by a hefty increase in the per-vehicle fine, from $5,000 to $25,000. With this change, GM could have been on the hook for $55 billion (with a "b") in fines for its bumbling of the ignition switch recall, rather than just $35 million. The News says, though, that NHTSA has "wide discretion" in handing out the fines. Considering a $55-billion fine is enough to sink any automaker, it is unlikely that such a monumental sum would be handed out. Still, the potential threat of such a death sentence should be enough for any automaker to sit up and take notice. "With millions of Americans behind the wheel every day, and more than 33,000 killed on our roads each year, we've got to do more to keep our cars and the roads we drive them on safe," McCaskill said, according to The News. "Painful recent examples at Toyota and GM have shown us we also must make it easier to hold accountable those who jeopardize consumers' safety. For too long, auto safety resources have remained virtually stagnant while cars and the safety challenges they present have become more complex." What do you think? Do you agree with McCaskill's proposed bill? Should the punishments for automakers and execs be more or less harsh? Have your say in Comments. News Source: The Detroit NewsImage Credit: J.
