Claim 9:
10. A solid oxide reversible fuel cell system comprising:
a solid oxide reversible fuel cell;
an air intake for providing air to the solid oxide reversible fuel cell;
a steam reformer fluidly coupled to the solid oxide fuel cell, the steam reformer having a catalyst;
a proton exchange member hydrogen pump configured to receive by-products from at least one of the steam reformer and the solid oxide reversible fuel cell, the proton exchange member hydrogen pump configured to form hydrogen gas from the by-products, wherein the steam reformer acts in a forward mode to produce hydrogen gas and a reverse mode to produce water and natural gas;
a low temperature heat exchanger coupled between the steam reformer and the proton exchange member hydrogen pump, the by-products form the at least one of the steam reformer and the solid oxide reversible fuel cell configured to flow through the low temperature heat exchanger before reaching the proton exchange member hydrogen pump; and
a blower coupled between an outlet of the low temperature heat exchanger and an inlet of the proton exchange member hydrogen pump, wherein the blower is configured to flow at least a portion of the by-products back to the low temperature heat exchanger.
