Power installation using fuel cells
First Claim
1. A method of generating electrical energy using a gaseous medium comprising the steps of:
- (a) passing a gaseous medium through a compressor unit;
(b) passing the compressed gaseous medium from the compressor unit through a flue gas heat exchanger in order to raise the temperature thereof;
(c) passing the gaseous medium through a gas turbine, the gas turbine being connected to the compressor unit;
(d) passing the compressed gaseous medium also into and through a fuel cell, the gaseous medium operable as an oxidizing agent to oxidize a fuel in the fuel cell, the fuel cell producing electrical energy from the oxidation of the fuel therewithin;
(e) passing the gaseous medium from the fuel cell through a further turbine, the gaseous medium passing out of the further turbine as exhaust, and;
(f) leading the exhaust from the further turbine through said flue gas heat exchanger.

Abstract
A method and installation is proposed for generating electrical energy in an open circuit for a gaseous fluid, comprising a compressor unit driven by a turbine receiving the compressed fluid after its passage through an exhaust gas heat exchanger, said method and installation further comprising a power generator driven by a gas turbine, the circuit also comprising a fuel cell receiving natural gas in its anode from an external source and receiving and gaseous fluid from the compressor unit as an oxidizing agent in its cathode, the electrical power originating from both the generator and the fuel cell forming the output of the method and installation.
