Abstract
A hybrid electrical power system includes a solid oxide fuel cell and a turbomachine. Fuel flow to the turbomachine is increased in response to demands for boost power, whereby the turbomachine's electrical generator provides the boost power. The turbomachine supplies heated, high pressure air to the solid oxide fuel cell, bringing the solid oxide fuel cell to its required operating temperature. Waste from the solid oxide fuel cell, including exhaust air and unreacted fuel, is utilized by the turbomachine.
