For fuel cells, gold is more precious than platinum

Scientists from the Department of Energy's Brookhaven National Laboratory found that nanoscale catalysts gold-cerium oxide and gold-titanium oxide are more efficient in producing purer hydrogen in fuel cell reactions than the expensive platinum-based catalysts.


These next generation catalysts could lead to cheaper fuel cells, which could lead to less expensive hydrogen-based automobiles, which could lead to less reliance in petroleum oil, which maybe could lead to world peace.
