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 cuts production target by 300,000 vehicles due to parts and chips shortages

TOKYO - Toyota cut its annual production target by 300,000 vehicles on Friday as rising COVID-19 infections slowed output at parts factories in Vietnam and Malaysia, compounding a global shortage of auto chips. "It's a combination of the coronavirus and semiconductors, but at the moment it is the coronavirus that is having the overwhelming impact," Kazunari Kumakura, an executive at the world's biggest car maker, said after the company revised its production target. Unlike other big global automakers that were forced earlier to scale back production plans, Toyota had managed to avoid cuts to output because it had stockpiled key components along a supply chain hardened against disruption following northeast Japan's devastating earthquake in 2011. Toyota's announcement on Friday is a further sign that no part of the global car industry has escaped the affects of a pandemic that has sapped sales and is hobbling its ability to take advantage of the recovery in demand that followed the initial waves of COVID-19. Car sales in China in August fell by almost a fifth from a year earlier because there were fewer vehicles for people to buy. Toyota now expects to build 9 million vehicles in the year to March 31, rather than 9.3 million. It did not revise its 2.5 trillion yen ($22.7 billion) operating profit forecast for the business year. Adding to a 360,000-vehicle cut in worldwide production in September, Toyota said on Friday it will reduce output by a further 70,000 this month and by 330,000 in October. It hopes to make up some of that lost production before its year-end. Demand for chips has soared during the pandemic as consumer electronic companies rush to meet stay-at-home demand for their smartphones, tablets and other devices. A heavy reliance on Southeast Asian factories for parts is a headache for Toyota, but its also a problem for its rivals that have struggled with what Volkswagen has described as "very volatile and tight" chip supplies. The German carmaker has warned it may need to cut production further as a result. Ford last month shut down production at a plant in Kansas that builds its best-selling F-150 pick up because of parts supply woes, with Renault extending partial stoppages at factories in Spain. Mercedes this month said it expects chip shortages to significantly lower third quarter sales.

Toyota calling for independent, industry-wide Takata airbag testing

The initiative is still very new, and there's no set timeframe for this third-party testing to begin. With Takata's airbag inflator recall expanding nationwide soon, the scope of this safety campaign is only growing, and is set to affect millions of additional vehicles. Toyota thinks that it can help, though. The Japanese automaker has announced an initiative to get all of the affected companies to band together to fund independent, third-party testing of the faulty components. The goal of this work is to "ensure the inflators that require replacement are accurately identified and promptly fixed," according to Toyota. All of the data would be shared among the participating automakers to better understand the causes of these problems, which still aren't entirely known, and come up with the best way to repair the affected vehicles. "By combining our collective efforts behind a coordinated, comprehensive testing program, we believe we can achieve greater results. Together we will be better equipped to address this issue more rapidly for all customers," said Simon Nagata, President and CEO, Toyota Motor Engineering and Manufacturing North America, in the company's release. According to Toyota spokesperson Cindy Knight speaking to Autoblog, the initiative is still very new, and there's no set timeframe for this third-party testing to begin. The automaker's first step is simply getting the word out that it's looking for partners. She said Toyota "has spoken with colleagues in the industry" about setting up the independent evaluations and specifically said the company has already reached out to Honda and Ford about possibly working together on this. Honda also released a statement calling for similar third party testing, and when reached for comment about Toyota's proposal, Ford spokesperson Kelli Felker responded: "Ford takes the safety of our customers very seriously. We plan to join the proposed industry wide effort to investigate and develop solutions to address this critical issue. We look forward to discussing next steps with NHTSA and other automakers."
