Metal-gas battery system

摘要

A metal-gas battery that utilizes an exhaust gas stream from a combustion engine as reactive gases is provided. Almost constant concentration of exhaust gases are supplied to the metal-gas battery via an existing engine systematic combustion system. The systematic combustion system keeps a definite air fuel mixture (A/F) that acts to enhance the fuel efficiency of the vehicle, and the metal-gas battery leverages the existing vehicle air management system. Exhaust heat of the exhaust gases is sometimes utilized for the heat control of the vehicle, and then the cooled exhaust gases are introduced into the metal-air battery to be consumed during a cathode reduction reaction to create and store electrical energy. The metal-gas battery supports the cleaning of exhausted gases using existing emission catalysts.

主权项

1. A metal-gas battery system comprising:
at least one metal-gas battery in fluid communication with an exhaust gas stream derived at least in part from an internal combustion engine and having at least one target emission component; wherein the exhaust gas stream is conveyed into the at least one metal-gas battery in a fashion that permits a portion of the at least one target emission component to be consumed during a reduction reaction of a cathode to produce energy; and wherein the at least one target emission component comprises O2 and at least one of CO2, CO, NOx, SOx, and hydrocarbon.
