SAE World Congress: Honda FCEV fuel cell stack has cells just 1 mm thin

The only update we have for people who are paying ultra-close attention to the progress of the hydrogen-powered Honda FCEV concept is that we now know how thin the individual cells in the car's fuel cell stack are. Speaking at the 2015 SAE World Congress in Detroit this week, American Honda Motor Company Manager of fuel cell vehicle marketing, Steve Ellis, told AutoblogGreen that the fuel cell stack is now 33-percent smaller and offers a 60-percent improvement in power density. We knew this already. What we didn't know is how Honda got there. Ellis said that these improvements are due in part to a reduction in the size of the fuel cell thickness. Each cell in the stack is one millimeter thick, he said. For everyone who isn't counting the millimeters of this car, here's the broader situation. Honda and the state of California (and others) are working hard on getting H2 infrastructure up can running. "The stations are accelerating as we speak," Ellis said. Three new stations have opened in the last few months and the state has pledged $20 million per year until there are 100 stations in California. Honda has also invested in FirstElement to install stations. The production FCEV will feature a range of over 300 miles and have a three-to-five minute refueling time. The car will launch in Japan in March 2016, with US and European sales starting at some unspecified time after that.

Acura NSX prototype gets back on track

Developing a new vehicle is not without its complications, we're sure, but usually things follow a fairly predictable progression: you develop a prototype, you test it, test it and test it again, then you put it into production. What you don't expect is that your prototype will burn to the ground, but that's what famously happened to the NSX which Honda engineers were testing a few months ago.
Fortunately, the Acura NSX prototype is back on track, both literally and figuratively, as you can see from this latest batch of spy shots snapped at the Nürburgring. This camouflaged prototype looks pretty much the same as the last one, only, you know... less crispy. Which is to say, it looks pretty much ready to hit showrooms.
The naysayers may point out that Honda chose colder and damper weather to put the NSX back into testing - thereby mitigating the risk of another fire - but we're sure the Japanese automaker has been working hard to fix the flammability issues, whatever may have caused them, over the past few months. At least, we hope they have.

Honda working on mid-engine sports car?

The NSX and new Civic Type R might not be the end of Honda's performance push. Patent images obtained by Autovisie in the Netherlands show the Japanese brand's possible design for another mid-engine sports car with what looks to be a removable top. According to Autovisie, the patent was registered on May 27 and was just released. However, nothing else official is known about the vehicle at this time. We can think of several possibilities as to what this might be. Honda is reportedly already working on the design for a future NSX convertible, although these images show significant changes to the overall shape compared to the coupe, which makes this possibility dubious. The automaker is also considering a performance model to slot below its halo car in the future, but without any scale, the size is hard to judge here. The S660 coming to North America is rumored as well, and maybe these shots are a redesign. Of course, the company's designers might just be toying around and patenting the shape for something else. This design definitely has a familial resemblance with the NSX and S660, and it looks great. Let us know in Comments what you think the vehicle might be.
