Discovery Could Make Fuel Cells Much Cheaper | Autopia | Wired.com: Researchers at Los Alamos National Laboratory have developed a platinum-free catalyst in the cathode of a hydrogen fuel cell that uses carbon, iron and cobalt. That could make the catalysts “two to three orders of magnitude cheaper,” the lab says, thereby significantly reducing the cost of fuel cells.
For those math dummies out there, 2 to 3 orders of magnitude means 100 to 1000 times cheaper.
