Abstract
A solid electrode in an electrolytic cell for rapid incorporation and exclusion of ions wandering to and from the electrode by way of an electrolyte with a minimum of voltage loss, in particular for a fuel cell, a high-performance battery, an electrochrome sign display unit or an electro-chemical storage element. The electrode comprises a structure having a higher electrical conductivity for electrons or holes than for the ions, and wherein the concentration of the electrons or holes movable within said electrode is lower than the concentration of the ions movable within the electrode.
