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 sizzle reel gives better look at i-Road Geneva concept

Toyota is taking the tiny tandem Tango to Tron town. In a teaser video for the new i-Road, debuting at the Geneva Motor Show next week, we catch a light-bike-like glimpse of Toyota's quirky tandem-seat concept. We still don't know much about the vehicle itself, but the video does flash the words "fun, compact, emissions-free," which suggests this is an electric ride. Then comes the apparent tagline: "i Roll, i Rock i Road." An indication that the tilting image we see in the video isn't just a special effect, perhaps? We'll have to wait until we get to Switzerland next week to find out. Until then, you can watch the video below.
In more earthly reveals, Toyota will also show off its hotly anticipate FT-86 Open sports car concept and Auris Touring Sports wagon on its Geneva show stand.

Junkyard Gem: 1991 Lexus ES 250

When the Lexus LS 400 first appeared here in late 1989 (as a 1990 model), sellers of German-made luxury sedans broke out in the shaky sweats and car shoppers flocked to see — and buy — this well-built statusmobile that retailed for about 60% of the price of the cheapest S-Class. Not attracting nearly as much attention at the time was the other introductory vehicle of the Lexus brand: the ES 250. Sold here for just the 1990 and 1991 model years, the first-generation ES was the most Camry-like of its kind and the hardest to find today. Here's a '91 in a San Francisco Bay Area yard. All of the ESs for the model's first couple of decades were based on the Camry, so they benefited from the Camry's famous reliability while suffering from its not-so-exciting image. Toyota made a good effort to make the 1990-1991 cars look something like their LS big brothers, but their Camry origins are quite obvious from most angles. Later ESs got more distinctive body panels and sales got stronger when that happened. Power came from this 2.5-liter V6, which was the hairiest engine available in the 1991 US-market Camry. 159 horsepower, which was pretty good for a car like this in the early 1990s. A five-speed manual transmission could be had in the ES 250 and ES 300 through the 1993 model year, but those early-1990s American car shoppers wishing for a midsize luxury sedan with three pedals generally opted for an Audi or BMW, with most of the rest settling on the Acura Legend. I'll keep looking out for a five-speed ES in a car graveyard, of course, but finding any first-gen ES has been a tough challenge in itself. This one got within 252 miles of the 200,000 mark, not bad for a typical 1991 car but also not especially impressive for a member of the Camry family. The interior was much nicer than what you got in any Camry, but junkyard shoppers have hit this one hard and its opulence no longer shines through. Toyotas had some variation of this switch from the late 1970s and into our current century. This version comes straight out of the Cressida. This content is hosted by a third party.
