    Report: Cheap metal-free catalyst could replace platinum in H2 fuel cells
    1372118220

    Some automakers want to get serious about bringing hydrogen-powered fuel cell vehicles to market if a big wall can be climbed – the one that puts the cost of H2 vehicles out of reach for some OEMs and at least $50,000 for others. That number could slide down thanks to researchers from South ...

    Report: Mullite mineral reduces diesel engine pollution by almost 50%
    1345898760

    People looking to maintain their health have long been advised to take their minerals. Will trucks be doing the same thing? Maybe. A mineral made from the oxide family has been found to cut diesel-engine pollution by as much as 45 percent and may be able to replace the use of platinum as a ...

    Nissan fuel cell vehicle on track for 2015
    1322600340

    With over 20,000 Leafs running around the planet, Nissan is looking to introduce yet another alt-powered vehicle to the world, and judging by its recent work with fuel cells, a hydrogen-powered vehicle could be here in four year's time. Today in Japan, Nissan showed off its next-generation fuel ...

    Report: Could 500 psi hydrogen storage tanks make H2 vehicles more feasible?
    1317038520

    The UK's first public-access hydrogen fueling station – the one opened by Honda just days ago – dispenses hydrogen at 350 bar (5,076 psi) and 700 bar (10,153 psi). The reason is that these are the two standard filling pressures adopted by the world's major automakers, and it requires ...

    Researchers theorize non-precious metal, "zero-cost" catalyst for fuel cells
    1304358660

    In a recent paper published in Science, a group of researchers has theorized that a non–precious metal catalyst, with performance that's claimed to be comparable to platinum-based systems, could some day end up in automotive fuel cells. Los Alamos National Laboratory researchers Gang Wu, ...

    Brookhaven National Laboratory working with photosynthesis and fuel cells
    1187826720

    U.S. Department of Energy's Brookhaven National Laboratory has got a few interesting projects going on right now that may be of interest to our readers. First is a project headed by chemist James Muckerman where the "goal is to design a bio-inspired system that can produce fuels like methanol or ...

    Cardiff University: recycling road dust for precious metals
    1184013720

    I don't know nearly enough about the mining of precious metals such as platinum to estimate how much it costs to get a reasonable amount from the earth. But, I do know that the metal is expensive to buy, so it must at least be reasonably difficult, right? So, perhaps we should be looking at ...

    Precious metals could make your catalytic converter more efficient and cheaper
    1176848820

    Gold, ah yes. The precious metal that adorns the majority of the population of the United States and other countries. We like it because of it's looks and the fact that it is rare. Which makes it expensive, unfortunately. But, not as expensive as platinum, another precious metal that is ...

    Thieves target catalytic converters for precious metals
    1164721800

    When I first heard about this type of theft a couple months ago, I thought it was an isolated incident. But in the last month I've found reports from Florida, Louisana, Tennessee and Michigan of similar actions: thieves are cutting out the catalytic converters on late-model vehicles to get at the ...

    Japanese researchers developing lower-cost fuel cell catalysts
    1161634020

    One of the drivers of the high cost of fuel cells right now is the need for platinum as a catalyst material. At the current price of just shy of $1,100 per ounce, the 100g of platinum required by a 100kW fuel cell accounts for about $3,500 of the cost. Researchers at the Tokyo University of ...

    Los Alamos scientists research cheaper, more durable fuel cells
    1159997520

    Yesterday, PhysOrg reported on the recently published fuel cell research of two Los Alamos scientists, Rajesh Bashyam and Piotr Zelenay, in the scientific journal Nature. Searching for a low-cost alternative to platinum, the duo developed a composite consisting of cobalt, polymer and carbon. The ...

    Future fuel cells may "digest" hydrogen
    1157674740

    The catalyst found in most fuel cells is composed of platinum, but Dr. Fraser Armstrong, a chemistry professor at Oxford University, believes that enzymes known as hydrogenases may hold the key to efficiently unlock the power of hydrogen.Armstrong says that hydrogenases are actually more effective ...
