Taiwanese researchers said they have developed hydrogen-powered mobile phone chargers. The device can recharge a mobile phone battery in two hours without being plugged, according to scientists at the Industrial Technology Research Institute in north Taiwan’s Hsinchu city. “Hydrogen is a recyclable material. The device is energy-efficient and will help protect the environment,” said Tsau Fanghei, a researcher at the institute. We will continue to improve the invention. We hope the hydrogen-powered device can replace current cell phone recharge systems in 2012.
