Fuel cell power production system with an integrated hydrogen utilization device

摘要

A fuel cell power production system and method for supplying power to a load, comprising a high-temperature fuel cell including an anode compartment, adapted to receive fuel from a fuel supply path and to output anode exhaust, and a cathode compartment adapted to receive oxidant gas and to output cathode exhaust, a water transfer assembly for transferring water in the anode exhaust to the fuel supply path and for outputting water-separated anode exhaust; and a hydrogen utilization device adapted to receive oxidant gas and one of the water-separated anode exhaust and gas derived from the water-separated anode exhaust and to output hydrogen utilization device exhaust including oxidant gas, wherein the hydrogen utilization device exhaust is used to provide oxidant gas to said cathode compartment.
