developed a way to avoid the use of expensive platinum in hydrogen fuel cells.\u00a0 <!--more-->The team found that non-precious\u2013metal catalysts comprised of carbon, iron and cobalt, could eliminate platinum.\u00a0 Such a catalyst could help solve the significant economic challenge that has thwarted the widespread use of hydrogen fuel cell systems.\u00a0 The new catalyst, in laboratory tests, yielded high power output, good efficiency, and promising longevity.\u00a0 It also generated currents comparable to platinum catalyst fuel cells, while also holding up favorably when cycled on and off.\u00a0 Piotr Zelenay, a Los Alamos researcher, said, &#8220;The encouraging point is that we have found a catalyst with a good durability and life cycle relative to platinum-based catalysts. \u00a0For all intents and purposes, this is a zero-cost catalyst in comparison to platinum, so it directly addresses one of the main barriers to hydrogen fuel cells.&#8221;\u00a0 The team\u2019s findings were published in the journal Science.<\/p>\n<p><a
