It is reported that the joint research team has developed a proton conductor for fuel cells. The conductor is based on polystyrene phosphoric acid and can maintain high proton conductivity at up to 200 ℃ and without water. The researchers of the team are from Los Alamos National Laboratory, the University of Stuttgart, the University of New Mexico and Sandia National Laboratories. Fuel cell is a promising technology, which can convert hydrogen into electricity through electrochemical process, and only drain wate
