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.
-- 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.
The MC Fill fast-fill protocol is designed for fuel systems that store hydrogen at a pressure of 700 bar (70MPa or 10,000 psi). This new fueling protocol reduces 700-bar fueling times by up to 45 percent versus comparable fueling protocols, and can complete most fills in less than three minutes under normal temperature conditions. The MC Fill more precisely monitors the dispenser outlet temperature and uses this information to calculate the shortest fueling time possible. This dynamic, fast-fill control not only provides FCEV customers with shorter fueling times, but it also allows the dispenser to continuously adjust to current temperature and other conditions which normally affect the refueling time.
Derived from two key values in a heat transfer equation-"M" for mass and "C" for specific heat-the MC Fill name refers to the heat capacity of the hydrogen storage system and represents the capability of the system to absorb the heat that is generated during fueling. The MC Fill protocol utilizes this value, as well as the dispenser outlet gas temperature and pressure, in its fill control logic.
"In order to meet customer expectations, hydrogen fuel cell-powered vehicles need driving ranges and fueling times comparable to conventional gasoline vehicles," said Steve Mathison, Senior Engineer at Honda R&D Americas, Inc. "This new fueling protocol will allow FCEV customers everywhere to realize short fueling times over a wide range of temperatures."
Honda has led the industry for nearly two decades in the development and deployment of fuel cell technology through extensive real world testing, including the first government fleet deployment and retail customer lease programs in the United States. Honda has also made significant technological advancements in fuel cell operation in both hot and sub-freezing temperatures and safety regulations, since the introduction of its first generation fuel cell vehicle, the FCX, in 2002. Honda launched its current fuel cell-electric vehicle, the FCX Clarity, in July 2008 as a real technological breakthrough in the areas of design, sedan packaging, assembly line manufacturing, and fuel cell stack size and efficiency, winning "World Green Car of the Year."
In November 2013, the new Honda FCEV Concept debuted at the Los Angeles International Auto Show, pointing the way to an all-new Honda fuel cell car launching in the U.S. and Japan in 2015 and later in Europe. Honda's next-generation fuel cell-electric vehicle will feature a fuel cell powertrain packaged completely in the engine room of the vehicle, allowing for efficiencies in cabin space as well as flexibility in the potential application of FC technology to multiple vehicle types in the future. The next-generation Honda FCEV is anticipated to have a driving range of more than 300 miles.
Honda Environmental Leadership
Honda is committed to further advancements in environmental technologies and the effort to improve fuel efficiency and reduce CO2 emissions from its products, including the 2014 Honda Accord Hybrid and Plug-In, the Fit EV, Civic Natural Gas and the Honda FCX Clarity fuel cell electric vehicle. Honda also has led the Union of Concerned Scientists' (UCS) rankings of overall vehicle environmental performance since 2000, and a Honda vehicle has been included on the list of America's greenest vehicles from the American Council for an Energy-Efficient Economy (ACEEE) for the past 16 years.
