+ - Hydrogen Fuel Cells for Smartphone Charging Coming in 2013->

Submitted by hypnosec
hypnosec (2231454) writes "The search for a hydrogen based cell phone charger is over as ROHM, Aquafairy and Kyoto University have developed a hydrogen based fuel cell that is capable of charging a phone in about 2 hours. Electricity in the compact and portable fuel cell is generated by producing hydrogen through a chemical reaction that involves calcium hydride sheets and water. The fuel cell generates approximately 4.5 liters of hydrogen from the calcium hydride sheet that is less than 3cc in volume thus providing 5Whr of electricity. ROHM said that the new fuel cell operate in ambient temperatures making it suitable for day to day use with smartphones, tablets, other portable devices."
