Hydrogen fuel cells work by introducing hydrogen and oxygen into the cell, which creates electricity to power the vehicle, and some of their benefits include water droplet emissions and a constantly charged battery. Learn more about the emissions and efficiency of hydrogen fuel cells with this free video from an automotive industry writer and editor.

  • We'll still need an aditional 1.21 gigawatts to power my flux capacitor.

  • Actually, you just got a very one-sided view.

    Hydrogen storage is a major problem. The mass of container needed to store a given amount of hydrogen is very high. All the video has to say is "we're getting better", because that's the best it can say.

    The membrane in the fuel cells is very expensive, as are the catalysts. The idea that the cost will come down by over an order of magnitude is dubious.

  • There is no way this can work. You simply cant get more out than you put in. If hydrogen is the answer, producing it this way makes no sense and the amount produced is so tiny it cant possibly make a significant difference.

  • Hydrogen is not a viable fuel unless it's produced by a renewable energy source, like solar. Otherwise coal will be the main source of the energy needed to produce hydrogen.

  • Plain hydrogen is even better.

  • LiPo batteries + Brushless outruner direct drive motors is the ONLY way to go.

    It's simple, inexpensive and very efficient.

    In less that 10 years we will be able to buy an electric car brand new for only $5.000 to $10.000

    STOP giving our tax money to GM and his friends (US oil companies)

  • The hydrogen needs to be produced from a fuel (no, water isn't a fuel. anyone who thinks it is should learn basic thermodynamics).  Considering this overall process, the advantage in energy efficiency and energy independence is dubious.

    Hydrogen fuel cells for automobiles were a huge area of research a handful of years ago and then fell out of favor. It wasn't politics that killed them, it was science and economics. Now, if science and economics can trump politics on ethanol...

  • Thanks Obama, cutting funds for hydrogen fuel cell research sounds like a great idea. DUMB
