Abstract

Disclosed is an improved method of reforming a gaseous reformable fuel within a solid oxide fuel cell generator, wherein the solid oxide fuel cell generator has a plurality of individual fuel cells in a refractory container, the fuel cells generating a partially spent fuel stream and a partially spent oxidant stream. The partially spent fuel stream is divided into two streams, spent fuel stream 1 and spent fuel stream 2. Spent fuel stream 1 is burned with the partially spent oxidant stream inside the refractory container to produce an exhaust stream. The exhaust stream is divided into two streams, exhaust stream 1 and exhaust stream 2, and exhaust stream 1 is vented. Exhaust stream 2 is mixed with spent fuel stream 2 to form a recycle stream. The recycle stream is mixed with the gaseous reformable fuel within the refractory container to form a fuel stream which is supplied to the fuel cells. Also disclosed is an improved apparatus which permits the reforming of a reformable gaseous fuel within such a solid oxide fuel cell generator. The apparatus comprises a mixing chamber within the refractory container, means for diverting a portion of the partially spent fuel stream to the mixingmore »« less

Non-pollutant fuel generator and fuel burner with a non-pollutant exhaust and supplementary dc generator. [for use in MHD generator, steam turbine, gas turbine, or fuel cell]

Patent Barros, M.J.

A system for generating non-polluting fuel and a burner for using such fuel to produce energy in the form of heat with a non-polluting exhaust, together with means for utilizing such exhaust to produce supplementary direct current power is disclosed. An electrolyzer is operated to produce hydrogen and oxygen in gaseous form which is then stored in suitable fuel tanks. As needed, the fuel is combined with air and supplied under pressure to a combustion chamber where the mixture is burned, producing heat and a pollution free exhaust. The heat so produced may be used as a conventional heat sourcemore »« less
