A portable fuel-cell requires only water to provide a steady stream of electrical energy.

MyFC has developed the PowerTrekk, a portable fuel cell that uses water to provide instant power to any device that can be connected through a USB cord.

Its fuel cell technology converts hydrogen into power. A fuel cell is an electrochemical device that transforms the chemical energy of a fuel (hydrogen, methanol, natural gas, gasoline) and an oxidant (air or oxygen) into electrical energy. Unlike batteries, fuel cells do not consume electrodes. As long as a fuel and an oxident are provided to a fuel cell's electrodes, it will keep producing electrical energy.
