Abstract:
1. A battery system, comprising: a reversible solid oxide electrochemical cell, wherein the reversible solid oxide electrochemical cell is capable of operating in a discharge mode and a charging mode; a storage tank, wherein the storage tank provides a fuel gas to the reversible solid oxide electrochemical cell when the reversible solid oxide electrochemical cell is in the discharge mode, and wherein the storage tank provides a reactant gas to the reversible solid oxide electrochemical cell when the reversible solid oxide electrochemical cell is in the charging mode, and wherein the storage tank further comprises a separation device that separates the fuel gas from the reactant gas; a fuel pump, wherein the fuel pump provides the fuel gas and the reactant gas to be stored in the storage tank; and a preheater, wherein the preheater heats the fuel gas provided to the reversible solid oxide electrochemical cell from the storage tank when the reversible solid oxide electrochemical cell is in the discharge mode, and wherein the preheater heats the reactant gas provided to the reversible solid oxide electrochemical cell from the storage tank when the reversible solid oxide electrochemical cell is in the charging mode; wherein the reactant gas comprises hydrogen gas, water, methane, carbon monoxide, and carbon dioxide and the fuel gas comprises hydrogen gas, water, and methane.
