Abstract
A method for fabricating a metal electrode from seawater and generating electric power with the metal electrode comprises steps: using a seawater treatment apparatus to heat seawater to a first temperature of 100-120° C. to obtain concentrated seawater; guiding the concentrated seawater to a precipitation apparatus, and adding a precipitation agent to the concentrated seawater to obtain a first crystalline material comprising magnesium hydroxide; heating the first crystalline material to a second temperature of 600-1100° C. to obtain a second crystalline material comprising magnesium oxide; transporting the second crystalline material to a separation apparatus, adding a reducing agent to the second crystalline material, heating the second crystalline material to a third temperature of 1200-2400° C. to obtain magnesium metal; and using the metal magnesium as a first electrode, and letting an electrolyte react with the first electrode and a second electrode to form electrochemical reactions and output electric power.
