  • Systems and methods to generate hydrogen and electrical power in a reversible compound fuel cell
    Patent number: 7255949
    Abstract: A hydrogen and electrical power generating system that includes a hydrogen source to generate a mixture having hydrogen gas, a ceramic fuel cell to generate power from a first portion of the mixture and a hydrogen separator to generate purified hydrogen gas from a second portion of the mixture using a protonic ceramic membrane. Additionally, a hydrogen and electrical power generating system that includes a hydrogen source to generate a mixture having hydrogen gas, and a reversible fuel cell capable of generating electrical power and purified hydrogen gas from the mixture, where the reversible fuel cell has a protonic ceramic electrolyte. Also, a method of generating hydrogen and electrical power that includes generating electric power from a first portion of a hydrogen gas mixture with a protonic ceramic fuel cell, and generating purified hydrogen gas from a second portion of the mixture with a hydrogen separator.
