ELECTRICAL CELL , ELEKTRISCHE ZELLE

The invention relates to an electrical cell (1) comprising• a reservoir (R) containing an electrolyte (EL),• a first electrode (E1), the first electrode (E1) being in electrical contact with the electrolyte (EL),• a second electrode (E2),• the second electrode (E2) being conductive and having a porous nano structure, comprising pores having a diameter of less than 1000 nm,• whereby the first electrode (E1) in comparison to the second electrode (E2) offers a different electrical potential of zero charge,• whereby the second electrode (E2) in operation is contacting the electrolyte (EL), such that the second electrode (E2) is wetted by the electrolyte (EL) due to capillary forces, whereby the electrolyte (EL) within the pores by means of the formation of electrical double layers provides an electrical current.
