With an injection of methanol, the fuel-cell generates electricity through a chemical reaction with oxygen to recharge mobile digital electronic devices via a USB cable.
The high-tech giant, which sees a bright future for fuel cells, said battery exhaustion had become a “major concern” due to the rising power consumption of mobile electronic devices.
It said the palm-sized fuel-cell, called Dynario, “delivers almost instant refuelling that untethers electrical equipment from AC adapters and power outlets.”
A single refill of methanol from a dedicated cartridge can generate enough power to charge two mobile telephones, said Toshiba today, which describes itself as a world leader in the development of fuel-cells for handheld gadgets.
The company will put 3000 of the devices on sale in Japan through its direct-order website at a price of 29,800 yen ($352) each.
The fuel cartridges cost an additional 3,150 yen ($37) for a set of five.
