BIOCHEMICAL SYSTEMS FOR SULFUR AND CARBON SEQUESTRATION

摘要

A fuel cell includes an anode including a current collector and microorganisms; a cathode; and a source of a sulfur-containing compound; wherein the fuel cell is poised for the microorganisms to selectively oxidize the sulfur-containing compound to elemental sulfur. Purification of a sulfur-contaminated fuel may be completed using such fuel cells. A method of carbon sequestration includes providing a fuel cell that includes a cathode including a conductor and oxygen; and an anode including a current collector and microorganisms; and introducing carbonic acid to the cathode to react with the oxygen to produce water and a carbonate or bicarbonate salt.
