Cobalt may substitute platinum in fuel cells
A team led by researchers at the Pacific Northwest National Laboratory in the United States designed a highly active catalyst that contains cobalt interspersed with nitrogen and carbon and, thus, doesn’t rely on platinum to spur the necessary chemical reaction. In a paper published in the journal Nature Catalysis, the scientists say that their invention is four times more durable than similarly structured catalysts made from iron —another platinum substitute. In their view, their findings show promise for fuel cells in transportation as proton exchange membrane fuel cells paired with hydrogen…
