Abstract
A power generating method of generating power supply by: guiding seawater through a reaction tank having negative electrodes made of magnesium or aluminum alloy and a positive electrode made of silver chloride, cuasing the negative electrodes to produce the oxidizing reaction of Mg→Mg+2+2e− and the positive electrode to produce the reduction reaction of 2AgCl+2e−→2Ag+2Cl−.
Claims3
A power generating method comprising the steps of:
- a) preparing a positive electrode by using silver chloride (AgCl) as a reduction reaction material;
- b) preparing two negative electrodes from a material selected from the group consisting of magnesium alloy and aluminum alloy by stamping, each negative electrode having a polymeric isolation layer;
- c) installing the positive electrode and negative electrode in a reaction tank having a seawater inlet and a seawater outlet such that the positive electrode is located between and spaced from the two negative electrodes, the polymeric isolation layers of each negative electrode facing the positive electrode;
- and
- d) filling the tank with seawater for use as an electrolyte, and producing electric energy by causing the positive electrode to produce the oxidizing reaction of Mg→Mg+2+2e− and the positive electrode to produce the reduction reaction of 2AgCl+2e−→2Ag+2Cl−, so as to obtain electric energy from the output of the electrodes.

A seawater battery comprising:
- a) a reaction tank having a seawater inlet and a seawater outlet for circulation of seawater through the reaction tank;
- b) two negative electrodes made of alloy material selected from a group of materials consisting of magnesium alloy and aluminum alloy, a first negative electrode being mounted on a top of the reaction tank and a second negative electrode being mounted on a bottom of the reaction tank;
- c) a negative output terminal made of a conductor wire and connected between the negative electrodes and extending outside the reaction tank;
- d) a positive electrode made of silver chloride (AgCl) and mounted inside the reaction tank and equally spaced between the two negative electrodes;
- e) a positive output terminal made of a nickel plate and connected to the positive electrode and extending out of the reaction tank;
- and
- f) a polymeric isolation layer mounted on each of the two negative electrodes and facing toward the positive electrodes to prevent electrical contact between the positive electrode and the two negative electrodes.
