Scientists Follow 150-Year-Old Trail to Clean Fuel of the Future

In a conventional hydrogen fuel cell, platinum is the preferred catalyst that sparks the production of electricity. The Los Alamos team found that their carbon-iron-cobalt substitute yielded currents comparable to platinum. It also compared well in other tests, such as durability when the fuel cell is cycled on and off, and efficiently converting hydrogen and oxygen into water. An inferior conversion process yields a large amount of hydrogen peroxide, an undesirable byproduct, aside from shortening the efficiency and lifespan of the fuel cell.
