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.

Honda installs 3-minute, fast-fuelling hydrogen fuel station in California

OK, but let's see how well Honda can control hydrogen refueling temperature in Houston or Buffalo. That's what some pessimists may be saying now that the Japanese automaker has installed a fast-fueling hydrogen station in the oh-so-temperate environs of Torrance, CA. That city is about 20 miles southwest of downtown Los Angeles and a sliver of it actually touches the Pacific Ocean, so we're not talking about wild swings in air temperature here. Honda is calling its fast-refueling platform the MC Fill (we'd expect a lawsuit if it was McFill, even though that'd be clever) and says that filling up takes about 45 percent less time than the typical hydrogen-refueling station. That's because the system monitors the ambient temperature in order to speed up the process. There's more scientific stuff in there - for example, the fact that the MC name comes from the "two key values in a heat transfer equation- 'M' for mass and 'C' for specific heat" - but the long and the short of it is that a hydrogen fuel-cell vehicle can fill up in less than three minutes. That's pretty impressive, despite the distinct lack of vehicles needing to charge that fast today. Honda unveiled its FCEV Concept vehicle at the Los Angeles Auto Show last November. The five-seat vehicle has a range of more than 300 miles, while its fuel-stack power density is about 60 percent higher than its previous version. The production version is due to arrive in the US in 2015. Check out Honda's press release below. Honda R&D Installs Advanced Fast-Fill Hydrogen Refueling Station -- New station on Honda R&D Americas' Torrance, California campus built in anticipation of Honda's next-generation fuel cell electric vehicle, due in 2015 -- Honda-developed hydrogen refueling protocol significantly reduces fill time TORRANCE, Calif., March 3, 2014 /PRNewswire/ -- Preparing for the 2015 introduction of the next Honda fuel cell-electric vehicle (FCEV), Honda R&D Americas has installed a state-of-the-art hydrogen refueling station on its Torrance, California campus. This advanced station will serve as a platform for demonstrating and validating the enhanced hydrogen fueling protocol developed by Honda, named the MC Fill. With the aim of standardizing this new protocol, Honda will make the new research station available to other automakers to further validate the MC Fill protocol's performance and functionality.

Honda making hydrogen from solar power in UK

Honda is going to launch a hydrogen-powered production vehicle (its second, really) next year, but the all-important H2 infrastructure question hasn't been fully answered yet. One possible solution is being tested over in the United Kingdom, where Honda is turning solar energy and water into hydrogen at its Swindon plant. SHD Logistics says the plant is the UK's "first commercial-scale hydrogen production and refuelling facility powered by solar energy." Despite the presence of an FCX Clarity in some pictures from the ribbon cutting, it's unclear if the station will be able to fuel any passenger cars. SHD Logistics talks about sending the hydrogen from where it is generated on the Honda plant grounds into the plant using 300-meter underground pipes so that hydrogen forklifts can refuel as needed. Two hydrogen fuel cell trucks used by Briggs Equipment UK, Honda's partner in the station, will also refuel at the plant. Honda said earlier this year that it, along with partner GM, would work to reduce the costs of a hydrogen refueling infrastructure. Solar-powered hydrolysis – which is what the Swindon facility uses – doesn't sound cheap to us, but at least it reduces the overall environmental costs, compared to using electricity generated from fossil fuels.
