A new fuel cell is 50 times as powerful as any other product that generates electricity from liquid methanol, thanks to improved catalyst and membrane technologies. The system can keep electric forklifts and other factory vehicles running for 16 hours. Compared with using electricity from coal-fired power plants to charge a battery pack, it reduces carbon emissions 66 percent.
