Are you still unclear about how exactly a hydrogen fuel cell works to power a car? Hyundai is offering a great visual on how its fuel cells operate in cars like the Tucson fuel Cell. Basically, the anode splits the hydrogen molecule into a positive and negative ion. The negative ions are used for electricity, while the positive ions are pushed through a membrane to the cathode, where both ions are combined with oxygen to create the byproduct of water. There's a little more to it than that to make it work in a vehicle, so see for yourself in the infographic below.

BYD is launching its T5 electric light truck in China. The truck has a maximum speed of 31 miles per hour, making it mostly suitable for in-city and campus duty. It has a range of almost 250 miles, though, and with its size, the T5 could make a pretty adept delivery truck. The battery is situated under the load bay between the axles, keeping the center of gravity low. Price could be an issue, but government subsidies might help convince some companies to make the switch to BYD's electric truck. See more over at Car News China.

The Mahindra Reva e2o electric vehicle will offer a fast charging feature, called Quick2Charge. Normally, the e2o takes five hours to fully charge, but that time gets cut to just one hour with the new option. Choosing the Quick2Charge option adds 45,000 rupees (about $735) to the price of the e2o. The new e2o is supposed to get electric power steering, and, later, a four-door variant. Mahindra Reva is also making an export-only version with Quick2Charge, longer range, electric steering, airbags, and ABS. Read more over at Indian Cars Bikes.

The Québec-Vermont Electric Charging Corridor is set to expand with 14 new charging stations. Mélanie Dufresne of the area's tourism board announced that the 240-volt chargers would be installed in Le Haut-Richelieu Regional County Municipality. Drivers will use a special access card to charge at the stations in the region for $2.50. The stations will be installed by the end of the year. To see all the locations and learn more about the announcement, head over to Hybrid Cars.

      Hyundai quality graphics don't explain how the 12v battery is maintained ( In the vehicle layout graphic behind the rear wheel / absent in other graphics. ) I guess it's easy to overlook things when making a Rube Goldberg vehicle ( You know like starting the vehicle, lights, wipers, & etc. ) Downvote away !!! hydrogen sock-puppets.

      Hyundai quality + fuel cells = what could go right ? BTW the BEV cons are why the hydrogen spambots are all over every Tesla Motors thread, Tesla Motors killed their talking points.

        Tesla CONS (referenced from graphic.) : 1) Range limited by driver / passenger bladder. 2) Overnight home charging / Supercharging. 3) Doesn't take up more space than other drive train combos. ( frunk / trunk ) 4) Performance comparable to other vehicles, weather-wise.

      No fuel cell cons Hyundai? Isn't that just a little bit misleading?

        Very misleading... especially "packaging (battery space)" The FCVs requires WAY MORE space than a battery EV. With battery cells, automakers can configure them smartly in efficient configurations (such as flat Tesla packs)... and leave lots of room for cargo and passengers. A Hydrogen tank must be cylindrical because of the laws of physics. Autoblog Comments Enhancer (ACE) v1.0.0 - bit.ly/Autoblog_Comments

          Hydrogen tanks can be different sizes, and hydrogen doesn't have to be stored in a tank. It really is a moot point though, because nobody is complaining about FCVs having reduced interior volume compared to other comparable vehicles.

        Im having trouble with the flow diagram at the beginning.. why generate water at all? why not just divert the hydrogen back into the fuel cell? :P

          In a nutshell, the hydrogen *has* to be combined with oxygen (to produce water) in order for the fuel cell to work.
