A fuel cell has been developed which uses ordinary water to provide up to 3W to battery powered products.
The device, called MyFC PowerTrekk, is based on micro fuel cell technology developed at KTH Royal Institute of Technology in Stockholm. Anders Lundblad, KTH researcher and founder of MyFC, said the charger is the first step toward building fuel cells in laptops. "The launch of our charger is a strategic move to gain wide acceptance of fuel cells throughout society." When water is poured onto a small disposable metal disc inside the unit, hydrogen is released and this combines with oxygen to generate electrical energy. The resulting charge is said to be enough to power an Apple iPhone to between 25 and 100% of its battery capacity. The device can also function as a portable battery.
