Abstract

Hydrocarbon fuel is sent to a reformer, which produces carbon and hydrogen. The hydrogen is sent to a fuel cell which uses it to generate electricity, and the electricity is used to actuate an electric motor that is coupled to an output shaft of a turbine to impart torque to the shaft. Additionally, hydrocarbon fuel can be provided to the turbine intake directly and/or carbon from the reformer can be mixed with steam from the fuel cell and sent to the turbine intake, in either case to impinge on the turbine blades and impart further torque to the output shaft.
