Abstract:
1. A method comprising: operating a solid oxide fuel cell that includes an anode flow field and a cathode flow field; exhausting the anode flow field and the cathode flow field into an exhaust flow field; directing a first portion of the exhaust flow field through a heat exchanger that includes an anode heat exchanger flow field and a cathode heat exchanger flow field; operating a fuel reformer; providing air at a first pressure level into a first fluid flow stream, the first fluid flow stream directing a first portion of the air to the cathode heat exchanger flow field and the cathode flow field; providing a second pressure level into a second fluid flow stream from a second portion of air from the first fluid flow stream, the second pressure level being greater than the first pressure level; generating a reformate stream from the fuel reformer by directing the second portion of air with the second fluid flow stream to the fuel reformer; and directing at least a portion of the reformate stream from the fuel reformer to the anode flow field.
