New Catalyst May Be a Boost For Fuel Cells

Roland Piquepaille writes "Researchers at the University of Houston (UH) have developed a new platinum-based catalyst for fuel cells that is at least four times more efficient and cheaper than existing catalysts. This discovery in fuel cell research may ease reliance on gasoline. According to the researchers, the active phase of the catalyst consists of nanoparticles with a platinum-rich shell and a core made of an alloy of copper, cobalt, and platinum. But it's not enough for this new catalyst to be more efficient and cheaper than a pure platinum one. It also needs to work for a long time — say, the life of a car. So far, the preliminary results look promising, but longer-term testing is needed before this kind of fuel cells can be used to power your car."

    For now, it's batteries. But in the not too distant future, it may well be supercapacitors. Supercapacitors now are about a factor of ten away from lithium-ion batteries; improvements that are currently in labs appear to be able to remove most or all of that gap. Right now supercapacitors are expensive, but once the market starts growing they should come down in price. There are relatively fundamental limits to how much better traditional batteries can get in terms of capacity, but the apparent limits on supercapacitors are phenomenal. It might be 10 years before they see serious use, but I imagine small-scale use will be here sooner than that, especially if the rumors are to be believed.

    Fuel cells are interesting, but I think that direct electrical storage through batteries and later supercapacitors is more likely to actually work out.

  2. Hydrogen is everywhere by benhocking · · Score: 4, Interesting

    You can get hydrogen from water, for example. It does require energy to extract that hydrogen, but you can use nuclear, wind, or solar power to perform that extraction. The reality is that oil is very unlikely to factor in to producing hydrogen. Unfortunately, coal is the most likely means for producing the requisite energy. For those whose only goal is to liberate us from dependence on Mid-East oil, it's a win. For those of us who care about the environment, it depends on what the energy source is, and is very likely a loss.
