An electrode boiler containing an aqueous electrolyte is provided with a pair of spaced electrodes immersed in the electrolyte and connected to an AC power source. Each electrode comprises an electrically conductive metal substrate having adhered to one face thereof a microporous electrochemically active mass comprising a reversible electrode couple covering essentially the entire face and being present in such quantity that at least some of each member of the electrode couple is present at all times during use. The electrodes are arranged with the active masses facing each other and in contact with the electrolyte. The electrode couple consists essentially of a material which is electrochemically reversibly oxidized and reduced in response to alternating current flow therethrough from one electrode to the other; thereby allowing high current density use without promoting corrosion or erosion of the electrodes. Examples of electrode substrate materials and electrode couples usable therewith are nickel and Ni(OH)2/NiOOH, copper and CuO/Cu(OH)2, and lead and Pb/PbSO4.
