Abstract:
An integrated fuel cell system, comprising:a first reactor adapted to receive a hydrocarbon feed and at least partially convert the hydrocarbon feed into a first fuel stream comprising a first hydrogen concentration and a first carbon monoxide concentration; a second reactor adapted to receive the first fuel stream from the first reactor and react a portion of the first carbon monoxide concentration with steam to produce a second fuel stream having a second hydrogen concentration and a second carbon monoxide concentration; wherein the second hydrogen concentration is greater than the first hydrogen concentration, wherein the second carbon monoxide concentration is lower than the first carbon monoxide concentration, wherein the second carbon monoxide concentration is at least 1,000 part per million; a fuel cell having a temperature of at least 120Â° C., wherein the fuel cell is adapted to receive the second fuel stream and react a portion of the second hydrogen concentration, wherein an exhaust from the fuel cell comprises at least 1,000 parts per million carbon monoxide; and an oxidizer adapted to receive the exhaust and oxidize a portion of the carbon monoxide in the exhaust.
