Many substances develop an electrical charge when in contact with an aqueous solution. This charged surface and the resulting charge distribution in the solution is known as the electrical double layer (EDL). DC electric fields exert coulombic forces on the EDL and can result in particle translation (electrophoresis) or bulk liquid motion (electroosmosis).

At the Laboratory for Energy and Microsystems Innovation (LEMI) we are using electrokinetic phenomena to realize robust, reliable fuel cell systems.
