"cut down proportion platinum used by 80 percent, set record in terms of cell's durability level... containing little platinum, new hybrid catalyst developed by the team managed to maintain the platinum catalytic activity at 97% after 100,000 cycles of accelerated stress testing, compared to the current catalyst which normally sees a drop of over 50% in performance after 30,000 cycles. In another test, the new fuel cell did not show any performance decay after operating for 200 hours"
