Embodiment Construction

[0045] figure 1 A system for energy generation according to the invention is represented.

[0046] The system includes an air source 1 for the air to be combusted, in this case ambient air. Other sources capable of supplying oxygen may also be provided where appropriate.

[0047]The system also includes a compressor assembly for compressing air. In this example, the compressor package includes:

[0048] - a low-pressure compressor 2 with an air inlet 3 and an outlet 4;

[0049] - A high-pressure compressor 5 with an inlet 6 and an outlet, the outlet 4 of the low-pressure compressor being connected to the inlet 6 of the high-pressure compressor 5 .

[0050] Furthermore, the system shown includes a compressor turbine assembly for driving a low pressure compressor 2 and a high pressure compressor 5, in this example comprising a single compressor turbine 8 with an inlet 9 and exit 10.

[0051] In this example, the air compressors 4 , 5 and the compressor turbine 8 are arrang...

Abstract

System having a plurality of high-temperature fuel cells connected in series for generating at least electrical energy, in particular having solid oxide fuel cells (SOFCs), which system comprises: - an air source for air, - a fuel source for a fuel, for example natural gas, - at least a first and a second high-temperature fuel cell, which are connected in series, each fuel cell comprising an anode inlet for fuel, and an anode outlet, as well as a cathode inlet for air, and a cathode outlet, as well as an electrical connection for outputting electrical energy which has been generated, - the cathode inlet of the first fuel cell being connected to the air source, - the anode inlet of each fuel cell being connected to the fuel source, - the cathode outlet of the first fuel cell being connected to the cathode inlet of the second fuel cell, - and a bypass air connection for air being provided between the air source, on the one hand, and, on the other hand, an admixing port between the cathode outlet of the first fuel cell and the cathode inlet of the second fuel cell.

Description

technical field [0001] The invention relates to a system with a plurality of high temperature fuel cells connected in series, in particular of the Solid Oxide Fuel Cell (SOFC) type, for generating at least electrical energy. Background technique [0002] It is known from the prior art that high-temperature fuel cells are suitable for "large-scale (distributed) energy generation". Fuel cells of this type including MCFCs (Molten Carbonate Fuel Cells) and SOFCs are currently believed to have operating temperatures above 600 degrees Celsius, and preferably between 650-1000 degrees Celsius in the case of SOFC fuel cells. The air is used to supply the fuel cells with oxygen, and the fuel used to supply the hydrogen can be, for example, natural gas or already produced hydrogen. [0003] Known systems comprising fuel cells of this type are not particularly satisfactory. The present invention does not relate to the design and manufacture of fuel cells of this type, but to methods o...
